Proof Scripts in JML

[mattulbrich]

Related Issue

For quite some time, we have a prototype for JML proof scripts which we finally want to bring to the mater branch.

Intended Change

Proof scripts can be written into JML comments and can be obeyed during automatic verification.
The major benefit is that the localisation of the proof node to which a proof script should be applied is natural.
The other benefit is that one can use JML expressions and thus does not have to leave the realm of JML to do script-guided proofs.

This relies on #3587 and needs #3654 merged.

Plan

• Refine the syntax
• Adapt lexer and parser
• Reimport the implementation that was available on an older branch
• Make it more convenient
• Add examples
• Code cleanup
• Document the changes

Type of pull request

• New feature (non-breaking change which adds functionality)
• There are changes to the (Java) code
• There are changes to the taclet rule base (possibly small adaptations)

Ensuring quality

WIP:

• I made sure that introduced/changed code is well documented (javadoc and inline comments). ✔️
• I made sure that new/changed end-user features are well documented (https://github.com/KeYProject/key-docs). ✔️
• I added new test case(s) for new functionality. ✔️
• I have tested the feature as follows: ... examples and test cases
• I have checked that runtime performance has not deteriorated. not for non-script proofs.

I have written an integer split command.

An induction command is on the way with support for int, user-data types, bsum(?).
