support -gz=zstd for both linker and assembler
PR driver/106897
gcc/ChangeLog:
* common.opt: Add -gz=zstd value.
* configure.ac: Detect --compress-debug-sections=zstd
for both linker and assembler.
* configure: Regenerate.
* gcc.cc (LINK_COMPRESS_DEBUG_SPEC): Handle -gz=zstd.
(ASM_COMPRESS_DEBUG_SPEC): Likewise.
