[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`.

[reland][libc] Remove UB specializations of type traits for BigInt (#84299)
Note: This is a reland of #84035.

The standard specifies that it it UB to specialize the following traits:
 - `std::is_integral`
 - `std::is_unsigned`
 - `std::make_unsigned`
 - `std::make_signed`

This patch:
 - Removes specializations for `BigInt`
 - Transforms SFINAE for `bit.h` functions from template parameter to
   return type (This makes specialization easier).
 - Adds `BigInt` specialization for `bit.h` functions.
 - Fixes code depending on previous specializations.

b555912e70 [libc] Better IntegerToString API
This patch is an alternative to D155902. It provides the following benefits:
 - No buffer manual allocation and error handling for the general case
 - More flexible API : width specifier, sign and prefix handling
 - Simpler code

The more flexible API removes the need for manually tweaking the buffer afterwards, and so prevents relying on implementation details of IntegerToString.
