Now a single beauty file is generated and used by all architectures,
remove the per-architecture Makefiles, Kbuild files and previous
generator script.
Note: there was conversation with Charlie Jenkins
<charlie@rivosinc.com> and they'd written an alternate approach to
support multiple architectures:
https://lore.kernel.org/all/20250114-perf_syscall_arch_runtime-v1-1-5b304e408e11@rivosinc.com/
It would have been better to have helped Charlie fix their series (my
apologies) but they agreed that the approach taken here was likely
best for longer term maintainability:

The definition of "static const char *const syscalltbl[] = {" is done
in a generated syscalls_32.h or syscalls_64.h that is architecture
dependent. In order to include the appropriate file a syscall_table.h
is found via the perf include path and it includes the syscalls_32.h
or syscalls_64.h as appropriate.
To support having multiple syscall tables, one for 32-bit and one for
64-bit, or for different architectures, an include path cannot be
used. Remove syscall_table.h because of this and inline what it does
into syscalltbl.c.
For architectures without a syscall_table.h this will cause a failure
to include either syscalls_32.h or syscalls_64.h rather than a failure
to include syscall_table.h. For architectures that only included one
or other, the behavior matches BITS_PER_LONG as previously done on
architectures supporting both syscalls_32.h and syscalls_64.h.

alpha uses a syscall table, use that in perf instead of requiring
libaudit.

perf currently fails to build on MIPS as there is no
tools/perf/arch/mips/Build file. Adding an empty file fixes this as
there are no MIPS-specific sources to build.
It looks like the same is needed for Alpha and PA-RISC, though I
haven't been able to test those.
