[roll] Roll fuchsia [roll] Roll llvm-project/libc [libc] Reland add getc, ungetc, fflush to enable libc++ iostream on baremetal (#183556)

After https://github.com/llvm/llvm-project/pull/168931 landed getc,
ungetc and fflush are still missing at link time while trying to make
libc++ std::cout work with LLVM libc on baremetal.

ungetc implementation is very minimal only to cover the current standard
streams implementation from the patch above.

The original PR https://github.com/llvm/llvm-project/pull/175530 caused
build failure on Windows because of too long command line in the
generated *.bat file which was fixed by
https://github.com/llvm/llvm-project/issues/182374
