Merge bitcoin/bitcoin#32027: cmake: Add NO_CACHE_IF_FAILED option for checking linker flags

52ac17757e cmake: Add `NO_CACHE_IF_FAILED` option for checking linker flags (Hennadii Stepanov)

Pull request description:

  Use it for checking `-fsanitize`.

  This change improves the user experience when the configuration step fails due to a missing library. Now, there is no need to manually clean the CMake cache after installing the required library.

  Addresses [this](https://github.com/bitcoin/bitcoin/issues/31942#issuecomment-2703801270) comment from https://github.com/bitcoin/bitcoin/issues/31942.
