RFR: 8356702: CTW: Update modules

[Evgeny Nikitin]

This PR enhances CTW test wrappers generator in order to make it more user-friendly. Added features are:

1. Automatic scanning for modules list under `open/src`
2. Automatic recognition of current year;
3. Multi-wrapper modules support (allows for splitting huge modules into 2 and more wrappers)
4. ability to exclude modules;

The updated generator have been used to refresh JTReg module wrappers.
The most meaningful change is contained in the `generate.bash`
Testing: `open/test/hotspot/jtreg/applications/ctw/modules` with the supported platforms, no failures spotted.
