perf: Move arch specific code into separate arch directory The perf userspace tool included some architecture specific code to map registers from the DWARF register number into the names used by the regs and stack access API. This moves the architecture specific code out into a separate arch/x86 directory along with the infrastructure required to use it.

perf tools: regs_query_register_offset() infrastructure regs_query_register_offset() is a helper function which converts register name like "%rax" to offset of a register in 'struct pt_regs', which is required by BPF prologue generator. PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET indicates an architecture supports converting name of a register to its offset in 'struct pt_regs'. HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET is introduced as the corresponding CFLAGS of PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET.
