Problem Summary: When building BE unit tests in LSAN+UBSAN mode, the linker
reports a duplicate symbol error for `__lsan_ignore_object`. The root cause is
that `phdr_cache.cpp` manually declares and defines `__lsan_ignore_object`,
which conflicts with the LSAN runtime library that already provides this
symbol. Additionally, `leak_annotations.h` only enables
`ANNOTATE_LEAKING_OBJECT_PTR` under `address_sanitizer` but not under
`leak_sanitizer` independently.
The fix:
1. Replace the manual `__lsan_ignore_object` declaration/definition in
`phdr_cache.cpp` with the existing `ANNOTATE_LEAKING_OBJECT_PTR` macro from
`leak_annotations.h`
2. Extend `leak_annotations.h` to also enable `ANNOTATE_LEAKING_OBJECT_PTR`
when `leak_sanitizer` is detected (not just `address_sanitizer`)
