* LambdaExpression.CanCompileToIL should respect IsDynamicCodeSupported

With the new feature switch added in https://github.com/dotnet/runtime/issues/39806, calling LambdaExpression.Compile is throwing a PlatformNotSupportedException. Instead, LambdaExpression should respect IsDynamicCodeSupported and switch to using the interpreter when IsDynamicCodeSupported is false.

* Add tests

Recent change in the `ThreadLocalModule::AllocateDynamicClass` has
accidentally removed zeroing for new  CollectibleDynamicEntry instances.
That leads to crashes when running code in an unloadable context.

This change fixes that.

Fixes https://github.com/dotnet/runtime/issues/79491

We were storing uninitialized values. Bug caught with valgrind, hopefully fixes some real crashes.

Grabbing custom attribute data brings the entire reflection stack (we need properties, constructors, fields, methods).

We ask `IsByRefLike` in type loader constraint validation. Ideally we should be able to get rid of the type loader from a hello world, but that's for later. This is a more efficient implementation either way.

Contributes to #80165.

Not aware of a good reason to keep using it. Removes `TypeDelegator` from apps that don't use it. Saves 7 kB (but also stepping stone for the larger savings later).

Remove the TypeKey concept as the primary user for the concept is unable to use it effectively. (#79418)

Contributes to #80165.

Dispensing of reflection member infos is done through a member policies class. This is a generic class that has specialized implementations for each kind of member info.

It used a clever trick to get to the specific implementations. Just access `MemberPolicies<EventInfo>.Default` to get one for events or `MemberPolicies<PropertyInfo>.Default` to get one for properties. It was also absolutely not trimming friendly.

This change removes the clever trick and replaces it with good old fashioned parameter passing.

    Make WriteCommentValue() overloads have same behavior.

Loop canonicalization now maintains pred edges. GC poll insertion was already
maintaining the edges but was rebuilding them anyways.

Now pred lists are never rebuilt.

Also revise `fgUpdateChangedFlowGraph` so that it no longer has the
ability to remove or rebuild.

Fixes #49030.
Also fixes #80772.

Fixes #47462 

**CoreCLR** This also makes some changes to CoreCLR to decouple EventPipe and startup hooks. Presently if startup hooks are disabled, `RuntimeEventSource.Initialize` is never called.  The PR makes the two features independent by moving runtime event source initialization out of the startup hook feature check.

* Implement startup hooks support in Mono

* Keep StartupHookProvider.ProcessStartupHooks under feature flag

* Don't catch/cleanup the exceptions from startup hooks.

* Add an ios simulator startup hook functional test

* Implement Android functional test

* Add WASM functional test

* Make a single managed startup method for CoreCLR

A common configuration for coreclr is event source enabled, startup
hooks disabled, so at least one managed call is inevitable.  Since we
have to call into managed no matter what, let the trimmer determine
what happens once we get there.

This is different from mono where published trimmed apps may have both
startup hooks and event source disabled.  In that case we would rather
avoid a managed call to an empty method early in startup.

* fix build and line damage

TreeLifeUpdater at most needs to flip 4 bits in two liveness sets when
it is called, however before this change it uses several full width
bitset operations to do this. This changes TreeLifeUpdater to do its job
in a much more direct way by updating the liveness sets directly.

jit-analyze no longer accepts comma-separated metrics after
https://github.com/dotnet/jitutils/pull/362, instead requiring each
metric to be specified separately on the command line.

* [mono][interp] Remove MINT_VT_ALIGNMENT

It serves no purpose nowadays. All vars are aligned to MINT_STACK_SLOT_SIZE.

* [mono][interp] Add 16 byte default alignment to optimized code

This will enable us to control alignment of Vector128 vars at compile time.

* [mono][interp] Add stack alignment for unoptimized code

For normal calls, we introduce a new opcode before the call that will move all the arguments to aligned stack location. When emitting the code for the call, we emit directly the aligned call args offset instead. Unoptimized code has its own opcodes that do moving of param, we tweak them to copy them into aligned location.

* [wasm] Enable dedup by default.

* [wasm] Enable symbol map for AOT tests too

* MonoAOTCompiler: Fix up the path for the output items if they had been

.. copied to `aot-in` for the compilation step.

Example:
- when using WasmDedup=true, we get the main assemblies in `publish`
directory after linking, but `aot-instances.dll` is in different directory.
- this causes `MonoAOTCompiler` to copy all of them to a temporary `aot-in` dir for compiling with `mono-aot-cross`.
- And when the output items are set, we get:

```
 Output Item(s):
     _WasmAssembliesInternal=
         obj/Debug/net8.0/browser-wasm/wasm/for-publish/aot-in/Debug_u4nbxx3i.gc5.dll
                 LlvmBitcodeFile=obj/Debug/net8.0/browser-wasm/wasm/for-publish/Debug_u4nbxx3i.gc5.dll.bc
```

- here the `ItemSpec` is incorrectly set to the temporary `aot-in` path
- which can cause build failures in the following build steps

* WBT: remove redundant case

This stress mode poisons all implicit byrefs before returns from the
method. GC pointers are nulled out and other parts of the structs are
filled with 0xcd bytes.

This should help expose incorrectly elided copies in the recently added
last-use copy elision optimization.

Fix #80731

Unlike seemingly all other ARM instructions, the set of instructions
marked by this PR actually write their result in the second operand
register instead of the first. This means we were incorrectly updating
GC info when emitting these instructions.
