  Revert "[compiler-rt][CMake] Enable TF intrinsics on powerpc32 Linux"

As mentioned in https://reviews.llvm.org/D121379#3690593, this
change broke the build of compiler-rt targeting powerpc using GCC.
The 32-bit powerpc target is not supposed to emit 128-bit libcalls
-- if it does, then that's a backend bug and needs to be fixed there.

This reverts commit 8f24a56a3a9363f353c8da318d97491a6818781d.

  Log Message:

These are new debug types that ships with the latest
Windows SDK and would warn and finally fail lld-link.

The symbols seems to be related to Microsoft's XFG
which is their version of CFG. We can't handle any of
this yet, so for now we can just ignore these types
so that lld doesn't fail with a new version of Windows

Fixes: #56285
