linux: Implement PTRACE_GETREGSET NT_PRFPREG and NT_X86_XSTATE
Implement NT_PRFPREG and NT_X86_XSTATE for PTRACE_GETREGSET on amd64.
Chrome's crashpad handler uses these to collect floating-point and
extended CPU register state for crash dumps.
Other architectures retain the previous EINVAL stub behavior.
