* Fix Crossgen2 PDB generator

During my perf investigation work I have found out that PDB emitter
in Crossgen2 is broken. I tracked this down to the change

https://github.com/dotnet/runtime/commit/fdf6485c800ec580656d7491795e10881d493afb#diff-24e48862e3b82f52e7fa04f22700b1c976a012bfeb08a246406f4e5ec579699b

that caused two behavioral changes in the PDB emitter:

1) The logic around QueryPDBNameEx got refactored to use a char[]
instead of a StringBuilder and that silently caused _pdbFilePath
to be set to the string "System.Char[]" instead of the actual path
(cf PdbWriter.cs#221 in the quoted commit).

2) The COM wrapper refactoring ended up bumping the refcount
on the _ngenWriter by one so that it never got actually closed
and properly flushed; due to this the resulting PDB was invalid.

VN was retaining the precise handle types when applying arithmetic
operations to handles. This meant that we could not rely on handles of
types like GTF_ICON_METHOD_HDL actually containing an embedded method
handle after constant propagation.

This change generalizes the handle type to GTF_ICON_CONST_PTR or
GTF_ICON_GLOBAL_PTR whenever VN does anything that semantically
"unassociates" the icon from the specialized handle type.

Some of the calls go through the trampoline infrastructure, which
cannot patch indirect calls made through GOT slots, causing crashes

Move some debug-only code to #if DEBUG, remove other dead code, and clean up a few things that are unnecessary.  Also add a few tests to fill out some code coverage results, and address some style-related comments from a recently merged PR.

* Address PR feedback

* Fix non-deterministic threading-related failures in regex tests

If the wrong tests run concurrently, they can end up seeing a changed NFA safe limit from another test.

* Increase precision and safety of the NonVersionableAttribute
- NonVersionable now only unconditionally affects whether or not the IL is reported as inlined in the inlining data
- Primitive types are now implicitly considered to be NonVersionable
- Classes defined in CoreLib may now be considered to be NonVersionable
  - Classes now marked are String, RawData, and RawArrayData, which are all tied into intrinsics in crossgen2
- NFloat is now marked as NonVersionable so that some of its methods may actually be treated as NonVersionable
- There is now an additional predicate that the IL within the NonVersionable method must satisfy a series of tests to ensure that it can safely be inlined without adding additional tokens for the logic to depend on. See below for the details of the predicate

Collectively these changes make it so that even if we change our inlining rules, the NonVersionable marked methods will successfully pass through Crossgen, without generating requiring tokens from their original modules to be present in the final image.

The rules are:
                // 1. ldfld, ldflda, and stfld to instance fields of NonVersionable structs and NonVersionable classes
                // 2. cpobj, initobj, ldobj, stobj, ldelem, ldelema or sizeof, to NonVersionable structures, signature variables, pointers, function pointers, byrefs, classes, or arrays
                // 3. stelem, to NonVersionable structures
                // In addition, the method must not have any EH.
                // The method may only have locals which are NonVersionable structures, or classes

* Address code review feedback

This change adds two build-only lanes to `runtime` and two full build+test lanes to `runtime-wasm` that builds wasm with internal threads only (`WasmEnablePerfTracing`) and full threading (`WasmEnableThreads`).

The `runtime-wasm` additions can only be manually triggered at this time.

* Convert incorrect assert for loading relative paths to native libraries

* Reenable PMI running on InteropServices tests.

We can use type info from GT_RET_EXPR nodes when deciding whether we
need to normalize on a return.

Fix #70334

We could also consider typing these GT_RET_EXPR nodes with the actual
type of the call, though I am unsure if we want to introduce more
small-typed nodes.

We no longer need to interop with JIT64 so clean up this TODO. We are in
fact already relying on the normalization done by the callee since we
allow tailcalling that skips the inserted normalization in R2R.

Such as those added by GDV.

The JIT will now clone just for type tests, or just for array bounds, or for
a mixture of the two. The JIT will still produce just one fast and one slow loop.
If there are a mixture of array bounds and type test conditions, all conditions
must pass for control to reach the fast loop.

Unlike array bounds checks, type test failures are not intrinsically rare,
so there is some profitability screening to ensure that a failed type test does
not force execution to run the slow version "too often". The type test must
execute frequently within the loop, and be heavily biased towards success.

This is work towards resolving #65206.

By default the JIT will dump blocks in bbNext order. This adds
other ordering options, specified by `JitDumpFgBlockOrder`:
* `0 (default) bbNext`
* `1 bbNum`
* `2 bbID`

`bbID` in particular is useful when comparing JIT dumps where blocks
have been reordered but the blocks themselves have similar content.

Rather than excluding all anchors, only exclude beginning anchors.
