Merge two similar hunks of code.

Also, unblock guarded devirtualization when prejitting, as we may see class
guesses via static PGO.

* Add ActivitySource.CreateActivity methods

* Address the feedback

* Add IdFormat parameter to ActivitySource.Create and fix the whole IdFormat logic

* Address @noahfalk feedback

Define PackageProjectUrl which is the public facing property to specify
a project url in a nuspec. Arcade defaults PackageProjectUrl to
RepositoryUrl if it isn't set. RepositoryUrl was incorrectly set to
git://github.com/dotnet/runtime instead of
https://github.com/dotnet/runtime which cause PackageProjectUrl to use
that incorrect value as well which ultimately results in nuget.org
failing package validation and refusing to add the package.

Also changing ProjectUrl to the previous https://dot.net value which is
the expected url to the dotnet project. In addition to that, specifying
Owners which aren't set anymore in 6.0.

Adding the ProjectUrl property as well as the
Microsoft.DotNet.Build.Tasks.Packaging package depends on it. That line
can be removed after the fix to not override its value unconditionally
is merged and consumed.

* Remove unnecessary msbuild-sdk from global.json

This line was meant to delineate between sdks that were auto-updated by different PRs. But we have since switched to no longer auto-update these SDKs, so there is no reason for this line anymore.

* Reorder so hard-coded entries are in the middle.

This avoids the disposable object creation for Rfc2989DeriveBytes and the
state tracking.

Since the one-shots just call into platform routines (when available) it
should allow for higher iteration counts for the same clock time.

Since the certificate names were the same, different tests were
colliding with caches since they had the same certificate name.

In addition to the simple fix, this changes the test to build a partial
chain using two intermediates. The leaf's issuing intermediate is
added to the ExtraStore and the second intermediate is expected
to be fetched by AIA (and fail with an empty response).

This is to help coerce chain builders treat it as a partial chain,
and can actually make some progress, as opposed to the leaf being
treated as an invalid root.

Make sure pal_icushim_static.c is linked in even if no symbols are used from it, so the EMSCRIPTEN_KEEPALIVE functions in it are actually kept. (#48550)

* Minor code clean-up in installer partition

* Move prepare-artifacts.proj into installer root

- The package is marked as non-shipping as we're not ready to make it part of the official product at this time, but this should make it easier to consume in downstream repos.

* [jit] Add a MonoJitMemoryManager structure, which is the same as the MonoJitDomainInfo structure, but owned by a MonoMemoryManager instead of a domain.

* Move static_rgctx_trampoline_hash to MonoJitMemoryManager.

* Move jump_target_hash to MonoJitMemoryManager.

* Move jump_trampoline_hash to MonoJitMemoryManager.

* Move jit_trampoline_hash to MonoJitMemoryManager.

* Move delegate_trampoline_hash to MonoJitMemoryManager.

* Move method_code_hash to MonoJitMemoryManager.

* Move more fields to MonoJitMemoryManager.

* Move llvm data to MonoJitMemoryManager.

* Move arch_seq_points field to MonoJitMemoryManager.

* Remove unused fields from MonoJitDomainInfo.

* Use the default alc memory manager only for now.

* Remove MonoJitDomainInfo which is now unused.

Mapping the package to `$(ProductVersion)` would be wrong in servicing cases. Hence just removing the hardcoded value entirely.

* Fix ThreadPool events validation test

* space

* Remove unaligned offsets for mapped layout

* Assert on windows only

- Unix will use the mapped layout with an offset for bundled assemblies
- Windows still should't create a mapped layout for bundles

* Delete publish-final.proj and delete unused installer.tasks files

* Avoid extra restore phase for tasks

The repo local tasks don't participate in the repo restore anymore,
hence avoiding the extra restore phase which should improve reliability
and build times.

The following sentence in the doc comments for the `IgnoreReadOnlyFields` member:

> A property is read-only if it isn't marked with the <c>readonly</c> keyword.

Should read:

> A field is read-only if it is marked with the <c>readonly</c> keyword.

* Fix another doc comment typo in JsonSerializerOptions.cs

The following sentence in the doc comments for the `IncludeFields` member:

> Determines whether fields are handled serialization and deserialization.

Should read:

> Determines whether fields are handled **during** serialization and deserialization.

And slightly rearrange the two bits of code that consider guarded
devirualization with the goal of eventually unifying them.

Fixes #48564.

* add disabling test policy

* Update docs/infra/buildtriage.md

* refactor interop classes

* move interop files to subdirectory

I have noticed that these two tests are still conditionally
executed on x64 only. I don't see why they shouldn't work on
other architectures.

* Add assembly name to SuperPMI collection

For each class, add JIT/EE calls to getAssemblyName so the SuperPMI
collections contain this information. This can be useful to try and track
down where a particular function in a large method context hive came
from.

Only do this when `COMPlus_EnableExtraSuperPmiQueries=1` is set.

Enable Hot Reload API on Linux

policy was always set to MONO_UNHANDLED_POLICY_CURRENT.  The
legacy (pre-.NET 2.0) policy was not used.

This method costs trees, which can in turn modify the IR by swapping operands.
As a result the bool value returned doesn't properly reflect whether any
changes happened.

This impacts proper reporting phase status by `optOptimizeLayout'. Since phase
status just gates post-phase dumps and checks, we'll just claim this phase
always modifies IR.

Add similar workaround for `optInvertLoops`.

Fixes #48495.
