[hwasan] Add hwasan-all-globals option (#149621)
hwasan-globals does not instrument globals with custom sections, because
existing code may use `__start_`/`__stop_` symbols to iterate over
globals in such a way which will cause hwasan assertions.
Introduce new hwasan-all-globals option, which instruments all
user-defined globals (but not those globals which are generated by the
hwasan instrumentation itself), including those with custom sections.
fixes #142442
