[TSan][OHOS] Support TSan for OHOS · Pull Request !380 · OpenHarmony/third_party_llvm-project

### Issue
https://gitee.com/openharmony/third_party_llvm-project/issues/I90RVC

### Reason (Purpose, Solved Problem)
Need to enable thread sanitizer in our toolchain to help with testing concurrency issues.

### Description
This enables TSan in clang driver for OHOS targets, for AArch64 and x86-64 architectures. Testing support is to be added in a subsequent PR.

This also disables interceptors on OHOS targets for some of the functions, which are not exported from our musl:
- `pthread_tryjoin_np`;
- `pthread_timedjoin_np`;
- `pthread_setcanceltype`;
- `pthread_setcancelstate` (it is exported, but currently only both of them with `pthread_setcanceltype` can be disabled, and presumably there is no point in intercepting one and not the other).

A side-effect is the addition of `-fno-emulated-tls` compilation flag to `sanitizer_common` library, because mutexes from there are used in TSan.

### Test (Local test)
With correct changes to the testing system, on AArch64 TSan tests pass, except for those which are incompatible either with musl (some functions not implemented or behavior different), or incompatible with OHOS version of musl (like `pthread_` functions listed above not being exported).

Edit: ASan and hwasan tests were checked to not be affected by this, other sanitizers currently are not supported without merged musl PRs.

### Need to cherry-pick to release (eg：monthly_20221018, OpenHarmony-3.2-Beta5 ...) branch？

- [ ] yes，branch list:
