Resolve assembler complains when including loongarch_arch.h

The assembler will complain when we include loongarch_arch.h in
an assembly file as following:

crypto/loongarch_arch.h: Assembler messages:
crypto/loongarch_arch.h:12: Fatal error: no match insn: extern	unsigned int OPENSSL_loongarch_hwcap_P

So, the sentence of `extern unsigned int OPENSSL_loongarch_hwcap_P`
should be guarded with "#ifndef __ASSEMBLER__".

Fixes #21838.
