Initialize method info early so that jitStress can use that information to determine when to enable stress.

Fix #8889

* Fix Diagnostics.Tracing ILLinkTrim entries

- PropertyValue/ReferenceTypeHelper's pattern is recognized by the ILLinker. Protected it with a new trimming test.
- RuntimeEventSource doesn't need to be rooted. This class is used by IL and doesn't get trimmed.
- EventPipe* and NativeRuntimeEventSource only need to be rooted in CoreCLR, since they aren't used in Mono. So they are moved to just CoreCLR's ILLinkTrim file.

Contributes to #35199

* First version of QCalls implementation, using QCalls on ICU Globalization.

* Stop ignoring CS1573 in multiple projects

* Fix interop.process.cs

* Update ZipFileExtensions.ZipArchive.Create.cs

IJW tests using a managed C++ component (TestLibrary) fail building
on Crossgen2 as the MSIL uses a special form of PInvoke without
specification of the target library (PInvoke into the unmanaged code
within the module itself) and that is currently unsupported in the
Crossgen2 metadata reader.

* Improve R2RDump output for ARM64.
Resolve targets of ADRP+ADD instruction pairs and BL instructions.
Also fix occasional \r\r\n in output for x86/x64.

* Handle other PC-relative instructions: ADR, B, CBZ, CBNZ, TBZ, TBNZ

* [browser][wasm] Add reference for those object that are created with ownsHandle false.

* Remove unnecessary special treatment for Global as it is no longer need.

We disable TermInfo library tests because the respective functionality doesn't make sense on WASM.

* Enhance DAC to allow getting AssemblyLoadContext for objects

This change adds support to DAC for getting AssemblyLoadContext
for a MethodTable. The returned AsseblyLoadContext is the context
into which the related type was loaded.

Also deleted some dead code

* Change Activity Default IdFormat to W3C

* Remove the prefix from the switch and fix a test

* address some of the feedback

* Scope the breaking change to .NET 5

* Fix running the test on NetFX

* Changed the define NET5 to W3C_DEFAULT_ID_FORMAT

* Add net5 and remove netstandard2.0 configuration in the package

* Return back netstandard 2.0 targetting

When removing it, caused a  CI source build failure

* Tweak XML comments on new GCMemoryInfo APIs

Various enum members and some new methods were missing doc comments.

* Update src/libraries/System.Private.CoreLib/src/System/GCMemoryInfo.cs

* Fix and cleanup dead indirections

The backend doesn't support a dead `TYP_STRUCT` indirection. Also, if a target register is needed, a `GT_IND` is better.

Fix #36237

* Add more WASM Substitutions

* Remove internal method

If we need to insert a COPY node to signify a temporary copy of field of a multi-reg lclVar, we need to set the appropriate last use bit.

Fix #37830

* Optimize memory allocations in ActivitySource

* revert back  using anonymous methods

* remove empty line

* Address the feedback

Perf improvements mostly for small or value-type POCOs

In Server GC when we allocate UOH objects and decide whether we should retry
when hardlimit is in effect we have an inconsistency between should_retry_other_heap
and virtual_commit. The former uses current_total_committed - current_total_committed_bookkeeping while the latter uses current_total_committed.
This causes us to be in a situation where we may have an infinite loop
since the allocate_uoh says to retry but virtual_commit fails.

* moving coMarshal type down

* add unix implementation

* setting default value for out params in unix

* remove unsafe

* new GetGCMemoryInfo API

This implements the new GetGCMemoryInfo API that provides much more info than the one we shipped in 3.0. Also added an overload to query GCs by kind - ephemeral, full blocking or BGC, to facilitate not having to keep a really small sampling interval but can still get the kinds of GCs that happen very infrequently.

Most of the changes inside GC are the following -

All the info is updated at the end of a GC with the exception of BGC which needs special care. We maintain 2 BGC info data structures and one could be in the process of getting updated and if the user requests either BGC info or the last GC info which is also a BGC, we would return the one that's complete. See comments in code for a more detailed explanation.

Fill in the after size data for all generations instead of just the affected generations.

Timing info recording -

+ Changed the GC time recording from ms to us. Previously we did the timing analysis with events which also carry their own high res timestamps so in GC using ms is good enough. But now since we are returning the timing info we want to record it in us instead of ms.
+ Consolidated when we get end_gc_time. It was not including all of the GC work before (eg, decommit eph seg). And moving it to do_post_gc makes it easier for getting the GC info.
+ Not including the EE restart time for blocking GCs - the reason being restart takes very little time and by the time we get to the actual RestartEE the GC settings could be changed and it's not worth the effort to wait till RestartEE at which point we have to spend more effort to figure out which GC to attribute it to.
+ Maintain the running % Pause time in GC info.

* Address review feedback

* Delegate cmake version check to cmake when possible
There are two kinds of old cmake versions:
* <ins>v3.13.0 onwards that support `-B` command-line option:</ins>
  cmake will print the error message based on `cmake_minimum_required`
  specified.
* <ins>< v3.13.0, which do not have `-B` option:</ins> cmake will fail
  before the version check with an obscure message, quite implicitly
  indicating that it doesn't understand `-B`. For that we have an
  up-front check just for `-B` option, covering the existence of cmake
  as well.

* Update eng/native/build-commons.sh

The PE issues that were causing issues in the multifolder test
on ARM64 have been fixed with

https://github.com/dotnet/runtime/pull/37518

so I'm reenabling the temporarily disabled test.

If a window update is received from the server between the time when we were creating an Http2Stream (initializing its available credit with the current initial window size) and when we stored the stream into the  streams dictionary, we might miss out on updating the stream's window size, which could in turn lead to stalls.
