perf parse-regs: Move out arch specific header from util/perf_regs.h
util/perf_regs.h includes another perf_regs.h:
#include <perf_regs.h>
Here it includes architecture specific header, for example, if we build arm64 target, the header tools/perf/arch/arm64/include/perf_regs.h is included.
We use this implicit way to include architecture specific header, which is not directive; furthermore, util/perf_regs.c is coupled with the architecture specific definitions.
This patch moves out arch specific header from util/perf_regs.h for generalizing the 'util' folder, as a result, the source files in 'arch' folder explicitly include architecture's perf_regs.h.

perf parse-regs: Remove PERF_REGS_{MAX|MASK} from common code
The macros PERF_REGS_MAX and PERF_REGS_MASK are architecture specific, let's remove them from the common file util/perf_regs.c.
As a side effect, the weak functions arch__intr_reg_mask() and arch__user_reg_mask() just return zeros, every arch defines its own functions in the 'arch' folder for returning right values.
Note, we don't need to return intr/user register masks dynamically, this is because these two functions are invoked during recording phase but not decoding phase, they are always invoked on the native environment, thus we don't need to parse them dynamically.
