Without that patch, I was having this errors 
```
error: implicit conversion changes signedness: 'long' to 'uintptr_t' (aka 'unsigned long') [-Werror,-Wsign-conversion]
```

1. When running the entire Pri1 test file I noticed that xUnit
sometimes generates an empty <assembly /> entry that was crashing
the new logic in run.py. I have added a check to harden the script
against this eventuality.

2. My logic to disable merged test wrapper build in BuildAsStandalone
mode wasn't completely correct - I used the CLRTestTargetUnsupported
property but that's ignored when CLRTestBuildAllTargets is set to
'allTargets'. I have changed it to DisableProjectBuild.

Thanks

Collect both non-pgo and pgo cases. For non-pgo, set OSR to trigger immediately
when any patchpoint is hit to maximize number of cases collected. For PGO, set
OSR to trigger once we've got a bit of profile data gathered by the Tier0 method.

According to the issue https://github.com/dotnet/runtime/issues/49247
a known pre-existing Crossgen2 bug is that it fails when presented
with the components of a previous Crossgen2 compilation in the
composite mode. This is because Crossgen2 lacks proper logic to
recognize the composite images and mistakes them for currently
unsupported managed C++ MSIL assemblies. This change adds the extra
check; I have also unified it between Crossgen2 and R2RDump.

Thanks

This change introduces test infra changes supporting new-style merged test wrappers.
As a first step in the test conversion the change switches over 1501 tests under the path
Loader/classloader/TypeGeneratorTests.

Just anotate couple other methods which I need, based on https://github.com/dotnet/runtime/pull/61259 methodology

Also add missing set description rendering for \d, \D

I was previously too aggressive in getting rid of concatenations in the comment rendering.  We would end up flattening concatenations into alternations erroneously.

If two threads race to initialize it, one may end up overwriting the others, which means state pushed onto the losing thread's stack might end up disappearing.
