build: enable ccache by default if available (#22020)
Initial benchmarks show that this gives a nice 50% compile time
reduction for neovim. This shouldn't affect users or CI, but it's a nice
speedup for local development. The C_COMPILER_LAUNCHER target property
is only supported by Makefiles and Ninja generators only, so this won't
give a speedup when using the Xcode and Visual Studio generators even if
ccache is available.
