Remove SetConsoleCtrlHandler from Unix PAL

Deleted SIGINT and SIGQUIT-related signal handling code, which means we no longer need to spin up a worker thread for all coreclr apps.

Make the debugger's SetConsoleCtrlHandler usage Windows-only (from offline conversation it sounded like we might choose to delete it entirely subsequently, but for now I've left it).

Removed all of the code related to SetConsoleCtrlHandler from the PAL.

Deleted all tests related to SetConsoleCtrlHandler from the palsuite.

Commit migrated from https://github.com/dotnet/coreclr/commit/810b1162fff85075feb6cd5dd47b30e9f668ad38

Fix sos clrstack unwinding for the special HelperMethodFrame.

Add and implement new ICorDebugDataTarget4 unwind interface using lldb stack unwinder ABIs. The implementation
does a linear search of the native frames for the stack pointer provided. It doesn't happen often so the
performance is fine.

Stub out the DBI's ICorDebugDataTarget4 (in ShimDataTarget::VirtualUnwind) for now. Since PAL_VirtualUnwindOutOfProc
is disabled it makes sense to just return E_NOTIMPL.

Fix bpmd command so it doesn't stop in lldb when it isn't a CLRN exception (continues).

Commit migrated from https://github.com/dotnet/coreclr/commit/cc1e6074bb7954f7e1913fd916a6fac571230c94

Fix handling of embedded scopes with multiple exception holders

During the exception handling pass 1 on Unix, we only find one holder for each
frame. But for the case where there are multiple scopes embedded in each other,
each of them having their own exception holder, this is not correct and we
need to call filters for all holders on such frame, starting from the inner-most
one.
This change fixes that.

In addition, it fixes one usage of the EX_CATCH_CPP_ONLY in the src/vm/threads.cpp
where the presence of the exception holder in the EX_TRY is not correct and causes
the exception handler pass 1 to consider the managed exception handled at that place.
The fix is to create a new EX_TRY_CPP_ONLY that doesn't contain the holder and use
it at that place.
In fact, the comment at EX_CATCH_IMPL_CPP_ONLY was suggesting that a separate EX_TRY
clone would be a better solution anyways, since it eliminates one try / catch level
in the EX_CATCH_IMPL_CPP_ONLY.

Add missing exception holder to EX_TRY

Commit migrated from https://github.com/dotnet/coreclr/commit/7a08037ba5c7d5858485985dcb1d4750c77d31a0

Add missing exception holder to EX_TRY

When the exception handling was changed recently, the exception holder
was added only to PAL_TRY / PAL_EXCEPT macros. But it needs to be
in the EX_TRY as well, otherwise first pass of exception handling
would incorrectly consider some exceptions unhandled.
