  [CMake] respect LLVMConfig.cmake's LLVM_DEFINITIONS in standalone builds (#138587)

In #138329, _GNU_SOURCE was added for Cygwin, but when building Clang
standalone against an installed LLVM this definition was not picked up,
resulting in undefined strnlen. Follow the documentation in
https://llvm.org/docs/CMake.html#embedding-llvm-in-your-project and add
the LLVM_DEFINITIONS in standalone projects' cmakes.

  -----------
  [LLVM][Cygwin] add workaround for blocking connect/accept in AF_UNIX sockets (#140353)

On Cygwin, UNIX sockets involve a handshake between connect and accept
to enable SO_PEERCRED/getpeereid handling. This necessitates accept
being called before connect can return, but at least the tests in
llvm/unittests/Support/raw_socket_stream_test do both on the same thread
(first connect and then accept), resulting in a deadlock. Add a call to
both places sockets are created that turns off the handshake (and
SO_PEERCRED/getpeereid support).

  -----------
  [MC] Restore MCAsmBackend::shouldForceRelocation to false

Revert the Target.getSpecifier implementation
(38c3ad36be1facbe6db2dede7e93c0f12fb4e1dc) and update SystemZAsmBackend
instead.

Many targets with %lo/%hi style specifiers (SPARC, MIPS, PowerPC,
RISC-V) do not force relocations for these specifiers.

Additionally, with the introduction of the addReloc hook,
shouldForceRelocation is not that necessary and should probably be
phased out.
