Allow overriding threadSelfRestrict* funcs with a macro
https://bugs.webkit.org/show_bug.cgi?id=276648
rdar://131809314
Reviewed by Justin Michaud.
The new OS_THREAD_SELF_RESTRICT and OS_THREAD_SELF_RESTRICT_SUPPORTED
macros can be used to locally override the default functionality,
regardless of runtime options or target, by just defining the
appropriate macros upstream of FastJITPermissions.h.
