cmake: Search for sccache too in CCache module sccache is a ccache rewrite that supports GCC, Clang and MSVC.

CMake: Fix CCache support when already using _LAUNCHER The official ccache documentation[1] recommends to set `CMAKE_C(XX)_COMPILER_LAUNCHER` to ccache to enable ccache. These also work as envionment variables (supported by CMake itself). However, using these instructions generates the following error during building: ccache: error: Recursive invocation (the name of the ccache binary must be "ccache") This is because Dolphin adds an additional command ccache layer (ccache ccache compiler ...). This fixes that issue by checking for `CMAKE_C(XX)_COMPILER_LAUNCHER` before inserting our own. Also, use `CMAKE_C(XX)_COMPILER_LAUNCHER` to add ccache because the CMake docs discourages the use of `RULE_LAUNCH_COMPILE` in favour of `CMAKE_C(XX)_COMPILER_LAUNCHER`.
