kernel: add new header gap_all.h

So far, most package kernel extensions `#include "compiled.h"` in order
to conveniently get access to (almost) all source headers of GAP at once
(which is nice for us because it means we are free to rename headers or
move stuff around between them without breaking kernel extensions).

But the result is rather counterintuitive: if one is not familiar with
this, seeing `#include "compiled.h"` in code is not at all clear. Also,
the original of `compiled.h` was to be included by C code generated by
`gac`, and it contains stuff we'd rather not encourage others to use.

Thus, add a new header `gap_all.h` containing all `#include` statements
formerly found in `compiled.h` -- this resolves all concerns.
