ubsan: remove UBSAN_MISC in favor of individual options
Make each UBSAN option individually selectable and remove UBSAN_MISC which
no longer has any purpose. Add help text for each Kconfig, and include a
reference to the Clang sanitizer documentation. Disable unsigned overflow
by default (not available with GCC and makes x86 unbootable with Clang).
Disable unreachable when objtool is in use (redundant and confuses things:
instrumentation appears at unreachable locations).
