Uses own Debug flag in zxbpp parser

This will allow using -d for zxbpp and enables debugging, or
-ddd in zxbc / zxbasm to enable debugging in zxbpp from them.

This way -ddd is required to show macros parsing (very verbose
and not related to the compiler) from the compiler, but only
-d when using the zxbpp directly.
