What does this PR do?

• Updates existing wrapper modules to be mostly in sync with the respective execution modules.
• Wraps most cp.* functions.
• Adds slsutil wrapper
• Adds defaults wrapper
• Adds log[mod] wrapper
• Adds cmdmod wrapper for cmd.script
• Makes cp.cache_file add the respective files to the filerefs archive that is sent to the minion during state runs

Based on #64576, which would have to be merged beforehand. Was merged.

Also substantially increases test coverage on the cp wrapper (Ref #64842). 23% -> >90%

Note: tests/pytests/integration/ssh/test_saltcheck.py::test_saltcheck_state is failing, but unrelated to this PR. git bisect shows it has been failing since 639ec02. -> reported as #65574

Previous Behavior

• Confusing behavior when module calls behave differently via salt-ssh than usual
• (see linked issues, many more would have been possible)
• Jinja imports in managed file templates would fail. The workaround was to specify extra_filerefs before applying states, either via CLI param or in the Saltfile. This PR allows to declare those dependencies in the state files themselves.

New Behavior

Works mostly the same as regular Salt.
