  [libc] Finetune libc.src.__support.OSUtil.osutil dependency. (#189501)

Several key targets unconditionally depend on `OSUtil.osutil` target,
causing errors when it is unnecessarily linked, or not available. This
PR fine-tuning the dependency on `OSUtil.osutil` to cleanly decouple
those targets, and gracefully skip targets that need `osutil`. Main
changes include:

* Make `LIBC_COPT_USE_C_ASSERT` to a cmake config, allowing
`LIBC_ASSERT` to use system's `assert` and not depending on `osutil`.
* Adjust cmake dependency for the following targets:
  - libc.src.__support.libc_assert
  - libc.src.__support.time.*
  - libc.src.time.linux.*
  - libc.src.unistd.*
  - LibcTest
* Give an option for `TestLogger` to use system's `fprintf` instead of
`osutil`.
