  [DTLTO][Clang] Add support for Integrated Distributed ThinLTO (#147265)

This patch introduces support for Integrated Distributed ThinLTO (DTLTO)
in Clang.

DTLTO enables the distribution of ThinLTO backend compilations via
external distribution systems, such as Incredibuild, during the
traditional link step: https://llvm.org/docs/DTLTO.html.

Testing:
- `lit` test coverage has been added to Clang's Driver tests.
- The DTLTO cross-project tests will use this Clang support.

For the design discussion of the DTLTO feature, see:
