refactor(ccache): Enable by default

Following [1] to get to this setup.

We setup all the ccache configuration before calling project() because
project will perform compiler checks. This is also why we can't use
message_colored here and print the colors manually

Before ENABLE_CCACHE was not yet defined when we reached the check in
01-core because the option was defined in 02-opts
