RFR: 8345259: Disallow ALL-MODULE-PATH without explicit --module-path [v4]

[Severin Gehwolf]

> Please review this extension to #22609 which now disallows `ALL-MODULE-PATH` without explicit `--module-path` option. In addition this fixes a bug mentioned in #22609 when `ALL-MODULE-PATH` and `--limit-modules` are used in combination it failed earlier and passes now due to alignment of `ModuleFinder`s. With this patch JEP 493 enabled builds and regular JDK builds behave the same in terms of `ALL-MODULE-PATH`.
> 
> When an explicit module path is being added, there is no difference. All modules on that path will be added as roots. Tests have been added for the same. Thoughts?
> 
> Testing:
> - [x] GHA, `test/jdk/tools/jlink` (all pass)
> - [x] Added jlink test.
