perf regs: Remove __weak attributive arch_sdt_arg_parse_op() function

In line with the previous patch, the __weak arch_sdt_arg_parse_op()
function is removed.

Architectural-specific implementations in the arch/ directory are now
converted into sub-functions within the util/perf-regs-arch/ directory.

The perf_sdt_arg_parse_op() function will call these sub-functions based
on the EM_HOST.

This change enables cross-architecture calls to arch_sdt_arg_parse_op().

No functional changes are intended.
