### What problem does this PR solve?
Problem Summary:
On glibc < 2.25, dynamic TLS can be allocated by libc and freed by
jemalloc, crashing during thread cleanup. Route all seven glibc
allocation entry points through the existing jemalloc wrappers, preserve
allocator API semantics, and add native interposition tests.
### Release note
Fix a BE crash during dynamic TLS cleanup on older glibc systems and
keep glibc allocation entry points paired with jemalloc.
### Check List (For Author)
- Test
- [ ] Regression test
- [x] Unit Test
- [ ] Manual test (add detailed scripts or steps below)
- [ ] No need to test or manual test. Explain why:
- [ ] This is a refactor/code format and no logic has been changed.
- [ ] Previous test can cover this change.
- [ ] No code files have been changed.
- [ ] Other reason
`./run-be-ut.sh --jemalloc-hook --run -j 2`: 12/12 passed on Linux
x86_64/glibc 2.32. Full BE, older glibc, ARM64 and customer JNI E2E were
not run.
- Behavior changed:
- [ ] No.
- [x] Yes. Glibc allocation entry points now consistently use jemalloc,
with allocator boundary semantics preserved.
- Does this need documentation?
- [x] No.
- [ ] Yes.
### Check List (For Reviewer who merge this PR)
- [ ] Confirm the release note
- [ ] Confirm test cases
- [ ] Confirm document
- [ ] Add branch pick label
