Another try of trying to land
https://github.com/llvm/llvm-project/pull/166382
- Fix some leftover tests checking for specific errnos
- Guard errno checking tests to not run on the GPU

The patch #166382 fixed most of these, but missed the fprintf_test ones.

Resubmitting https://github.com/llvm/llvm-project/pull/162876 with fixes
as it broke some buildbots:
- Fix comparisons of integer expressions of different signedness
- Not check for specific errnos in tests, as they might not be available
on all platforms

[#159474](https://github.com/llvm/llvm-project/issues/159474)
- All printf variants set errno and consistently return -1 on error,
instead of returning various predefined error codes
- Return value overflow handling is added

In a previous patch, the printf writer was rewritten to use a single
writer class with a buffer and a callback hook. This patch refactors
scanf's reader to match conceptually.

This patch adds targets for printf and fprintf to the bazel build.
Additionally, it adds support for the build system to specify where
files should be written for testing purposes. This was necessary to
enable the fprintf test under bazel.

The printf and fprintf implementations use our internal implementation
to improve performance when it's available, but this patch enables using
the public FILE API for overlay mode.

This part of the effort to make all test related pieces into the `test`
directory. This helps is excluding test related pieces in a straight
forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move
the MPFR wrapper and testutils into the 'test' directory.

Add return values to converter functions to allow for better error
handling when writing files. Also move the file writing code around to
be easier to read.

This patch adds the file_writer header, which just provides a wrapper
for File->write, as well as fprintf to use it. There are no unit tests
for file_writer since it's too simple to need them, but fprintf does
have a simple test of writing to a file.
