doc: Move description of preprocessor mode before direct mode

This way the depend mode is documented directly after the direct mode
which makes more sense since they are related.

 ccache has two ways of gathering information used to look up results in the
 cache:
 
-* the *direct mode*, where ccache hashes the source code and include files
-  directly
 * the *preprocessor mode*, where ccache runs the preprocessor on the source
   code and hashes the result
+* the *direct mode*, where ccache hashes the source code and include files

 The direct mode is generally faster since running the preprocessor has some
 overhead.
