perf python: Disable -Wno-cast-function-type-mismatch if present on clang
commit 00dc514612fe98cfa117193b9df28f15e7c9db9c upstream.
The -Wcast-function-type-mismatch option was introduced in clang 19 and
its enabled by default, since we use -Werror, and python bindings do
casts that are valid but trips this warning, disable it if present.
