compile.h: stop using mrbc_ prefix for compiler context

Since it is confusing that the term `mrbc` stands for both "mruby
compiler" and "mruby compiler context" in the source code. Instead,
we use `mrb_ccontext` (stands for compiler context) prefix hereafter.

We choose `mrb_ccontext` because we have already used `mrb_context` (for
VM execusion context).
