Subject: [PATCH] build: Remove `cmake/script/CoverageFuzz.cmake`

The `gcov`-based `CoverageFuzz` script was introduced in
8b6f1c4353836bae6aa683cbc65251165bd031ba, 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 change removes the never-documented `CoverageFuzz` script, which is
likely unused.
