In commit 74b5fae (Clang: Use -fno-ansi-escape-codes for color
diagnostics on Windows, 2023-10-19, v3.28.0-rc3~3^2) we added the
positive option `-fansi-escape-codes` and the negative form of
the option, `-fno-ansi-escape-codes`.  According to the LLVM/Clang
documentation:

* https://releases.llvm.org/18.1.4/tools/clang/docs/UsersManual.html#cmdoption-fansi-escape-codes

only the positive form of the option exists.

Fixes: #26036

The `GoogleTest` module needs this to pass the `TEST_EXECUTOR`
definition to its `GoogleTestAddTests.cmake` helper script in
the `POST_BUILD` command since commit f875c47 (GoogleTest: Honor
TEST_LAUNCHER in gtest_discover_tests, 2024-01-17, v3.29.0-rc1~34^2).
Previously it worked only if other characters, such as spaces,
caused the argument to be quoted.  This was exposed by running the
`RunCMake.GoogleTest` test in a path without spaces.
