perf unwind: Change fixed name of libunwind__arch_reg_id to macro
For local libunwind, it uses the fixed methods to convert register id
according to the host platform, but in remote libunwind, this convert
function should be the one for remote architecture. This patch changes
the fixed name to macro and code for each remote platform can be
compiled indivadually.
