ArmPkg/DebugPeCoffExtraActionLib: Drop RVCT and Cygwin support

The DebugPeCoffExtraActionLib implemention in ArmPkg contains some cruft
that dates back to the original RVCT based ARM port, and support for
RVCT was dropped a while ago.

Also drop the handling of Cygwin specific paths, which is highly
unlikely to be still depended upon by anyone.

Tweak the logic so that only two versions of the DEBUG() invocations
remain: one for __GNUC__ when PdbPointer is set, and the fallback that
just prints the image address and the address of the entrypoint.
