dump: Simplify compiling win_dump.o by introducing win_dump_available()
To make dump.c less target dependent, move the TARGET_X86_64 #ifdef'ry from dump.c to win_dump.c (introducing a win_dump_available() method there). By doing so we can build win_dump.c on any target, and simplify the meson rule.
