00a5f9b737 build: Remove `cmake/script/CoverageFuzz.cmake` (Hennadii Stepanov)

Pull request description:

  The `gcov`-based `CoverageFuzz` script was introduced in 8b6f1c4353, as a CMake's replacement for the legacy `cov_fuzz` target. However, neither `cov_fuzz` nor `CoverageFuzz` has a documented usage.

  Instead, #32206 documented compiling for fuzz coverage using the LLVM/Clang toolchain, which does not involve the `CoverageFuzz` script.

  This PR removes the never-documented `CoverageFuzz` script, which is likely unused.
