machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h.

Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which
always comes from sys/types.h. And, really, sys/types.h (or at least
sys/stdint.h) is needed for uintN_t and uintptr_t.

machine/mutex.h: Sprinkle includes so this can be used by crash(8).

XXX pullup-10

branches: 1.7.4;
Nix trailing whitespace in files of membars, atomics, and lock stubs.

Will be touching many of these files soon for functional changes.

No functional change intended.

- In kern_mutex.c, if MUTEX_CAS() is not defined, define it in terms of
atomic_cas_ulong().
- For arm, ia64, m68k, mips, or1k, riscv, vax: don't define our own
MUTEX_CAS(), as they either use atomic_cas_ulong() or equivalent
(atomic_cas_uint() on m68k).
- For alpha and sparc64, don't define MUTEX_CAS() in terms of their own
_lock_cas(), which has its own memory barriers; the call sites in
kern_mutex.c already have the appropriate memory barrier calls. Thus,
alpha and sparc64 can use default definition.
- For sh3, don't define MUTEX_CAS() in terms of its own _lock_cas();
atomic_cas_ulong() is strong-aliased to _lock_cas(), therefore defining
our own MUTEX_CAS() is redundant.
