Fix GenTree hash function for commutative operators

gtHashValue() computes a hash value for a tree that, at least now,
is only used for determining whether to display the tree in the
JitDump after morphing. The hash function for commutative binary
operators was designed to return the same value if the operands
were switched (possibly this was used for CSE previously?). However,
this means that in some cases, nearly symmetric operands before and
after morphing would cause the "after morph" tree not to be displayed,
which is very confusing, since it implies that morphing had no
effect on the tree.

Since it appears we have no need for this special handling of
commutative binary operators, remove the special hashing done for them.

Fix debugger launch race hitting breakpoints in startup code. (dotnet/coreclr#8951)

The attached flag was been set asynchronously relative to the DebugActiveProcess
returning.  This could cause a race where the initial module load notification being
missed/not sent to the debugger.

This fix sets the attached flag before any notifications sent during launch if the runtime was
launched/attached using the startup handshake after dbgshim tells the runtime to "continue"
when the runtime startup API callback returns.

Also fixes another race condition in dbgshim where EnumerateCLRs returns a NULL continue event
handle because the coreclr module was loaded but the g_hContinueStartupEvent wasn't initialized
on the runtime side yet. Changed the static initialization of g_hContinueStartupEvent to
INVALID_HANDLE_VALUE and the InternalEnumerateCLRs sleep/retry loop to retry when any of the
handles are INVALID_HANDLE_VALUE. This fixes the race only when you have the latest dbgshim
and coreclr binaries and the old/new mixes still function but don't fix the race.

Fix incorrect comment

Rewrite bogus reference to nonexistsent `m_HeapDef` to correctly refer to
`block->bbHeapDef`.  Also change "doesn't kill heap" to "doesn't kill heap
liveness" (since it still kills availability).

Also add clarifying comments where `bbHeapUse` and `bbHeapDef` are
declared.

Remove PLATFORM_UNIX and FEATURE_PAL checks in PAL (dotnet/coreclr#8982)

This change removes all ifdefs for PLATFORM_UNIX and FEATURE_PAL
from PAL and also removes dead code that was never compiled in PAL
due to both of them being always defined for PAL.
