Resolve assertion failure in LSan

[kleisauke]

By re-syncing lsan_common_emscripten.cpp with lsan_common.cpp,
except for the guard page skip logic (IsAccessibleMemoryRange
always returns true on Emscripten).

The added test case in PR #14481 seems to trigger this assertion
failure:

[kleisauke]

CI failure in posixtest looks unrelated and also happens on the main branch (see e.g. https://circleci.com/gh/emscripten-core/emscripten/444387).

[kripken]

I restarted it, and looks like it passed.
