Mark Johnston 2b76d0699e Simplify kernel sanitizer interceptors 
KASAN and KCSAN implement interceptors for various primitive operations
that are not instrumented by the compiler.  KMSAN requires them as well.
Rather than adding new cases for each sanitizer which requires
interceptors, implement the following protocol:
- When interceptor definitions are required, define
  SAN_NEEDS_INTERCEPTORS and SANITIZER_INTERCEPTOR_PREFIX.
- In headers that declare functions which need to be intercepted by a
  sanitizer runtime, use SANITIZER_INTERCEPTOR_PREFIX to provide
  declarations.
- When SAN_RUNTIME is defined, do not redefine the names of intercepted
  functions.  This is typically the case in files which implement
  sanitizer runtimes but is also needed in, for example, files which
  define ifunc selectors for intercepted operations.
