Use CompilerForCAP to compose Julia function calls in Julia instead of GAP

[zickgraf]

Depends on homalg-project/CAP_project#552

See commit messages for details. Commits should be reviewed separately.

In concrete applications some issues might arise:

1. The same things might get computed multiple times for Source, Range and UnderlyingMatrix of a morphism.
2. Code containing Lift/Colift cannot be compiled well because of the special case "fail".
3. I'm not 100% sure that Julia actually inlines all the functions I create.

The first two issues could be fixed by different means -> I need concrete applications instead of toy examples to weigh the possible solutions. For the third issue I need someone with more knowledge of Julia than I have.

homalg-project/CAP_project#552 is merged, so in principle this is now ready for review. However, I'm not sure how to make the code in gap/CompilerLogic.gi "reviewable". It uses CapJitIterateOverTree, which has documentation in CompilerForCAP, but this is rather technical and requires knowledge of GAP's syntax trees (which lack documentation as mentioned before).
