* Delete System.Runtime.Experimental leftovers

e34e8dd8 merged the API surface of System.Runtime.Experimental inbox and deleted the project and the package. Hence we should delete leftovers that reference it.

* Update System.Runtime.csproj

* [mono][interp] Enable all IL_Conformance tests

* [mono][interp] Enable tests

* [mono][interp] Enable test

* [tests] Fix ckfinite test

According to spec, ckfinite can throw ArithmeticException. CoreCLR throws OverflowException while mono throws ArithmeticException. Change test to catch all ArithmeticExceptions.

`UnmanagedPdbSymbolReader` will already perform a GUID check that rejects mismatched symbol files. Do the same for the portable symbol reader.

This is mainly motivated by the March 2022 release of .NET 5. .NET 5 was
found to be vulnerable to CVE-2020-8927, which was caused by the older
version of brotli built into .NET. .NET was vulernable even in
environments where a system-wide version of brotli was present and had
already received fixes for this CVE. We could have avoided a Remote Code
Execution vulnerability in such environments by using the system's
version of brotli.

This is similar to the existing support for disabling distro-agnostic
OpenSSL (except no OpenSSL is embedded) and using the system libunwind
(a copy of libunwind is embedded this repo).

One small twist is the presence of entrypoint verification. In a
system-brotli build, the verification fails, because the built library,
libSystem.IO.Compression.Native.so, doesn't include the symbols for
Brotli. Those symbols are instead used from the system brotli libraries.

When adding tracing to the Linux X509Chain build, the "when do we process revocation" check got cleaned up to avoid doing wasteful work. But it got cleaned a bit too aggressively.

With this change, fully-valid and valid-except-for-validity chains will both move into active revocation checks.

The m_lastDispatchedIBEvent was not being cleared during shutdown, which was causing a memory leak assert to fire.

* Add shell to the environment

Environment setting https://github.com/emscripten-core/emscripten/blob/2.0.34/src/settings.js#L616-L641

From emscripten 2.0.25 release notes

    - Support for the 'shell' environment is now disabled by default.  Running under
      `d8`, `js`, or `jsc` is not something that most emscripten users ever want to
      do, so including the support code is, more often than not, unnecessary.  Users
      who want shell support can enable it by including 'shell' in `-s ENVIRONMENT`
      (#14535).

Example of the the size increase for bench sample:

* Include method instantiation MethodTables in compilation

We'll need to load the `MethodTable` so that we can search for it in GVM tables.

* Regression test

* Cleanup obsolete 32 bit related macOS code

* Cleanup obsolete mac OS 32 bit stuff

I've noticed that we had some stuff in our PAL that was there from
the era of the 32 bit mac OS, so I have removed it.

Also upstreamed a fix for libunwind https://github.com/libunwind/libunwind/pull/342 (but we are not using ptrace so it can wait until the next libunwind update).

* [wasm] Do not set _WasmDevel=true for blazor projects

to workaround wasm-ld getting oomkilled.

Fixes https://github.com/dotnet/runtime/issues/66725, and https://github.com/dotnet/runtime/issues/66591

* Fix test

LLVM already assumes the `char*` it receives is UTF-8. Fixes #66913.

The trimming settings for .NET 5 are not compatible and lead to rooting everything. Who knows what else is not compatible. We don't test this.

* Fix some alloc-dealloc mismatches found by ASAN

* Define new static

* remove unused code

* fix osx build

* android

* Fix warnings introduced by new version of trim analyzer

In the case of Type.Helpers.cs better data flow analysis in the analyzer uncovers a warning. The method is used to implement reflection functionality and the warnings are not a problem and should be suppressed.

In the case of the System.Private.Xml Types.cs, the analyzer shows a real issue where the annotation is not enough for what the method does. This changed the annotation to All - which is already in place in all the callers anyway.
