Strict syntax support

[nvnieuwk]

This pull request attempts to fix all strict syntax related issues. There are still some small issues but most problems have already been fixed. Feel free to take a look already :)

TODOs:

• Fix errors when running with NXF_SYNTAX_PARSER=v2
• Add or update tests

[nvnieuwk]

Functions in the lib folder don't work with the current implementation, looking into it right now

Thank you so much for your help!!

[nvnieuwk]

This should be ready now!

[lukfor]

Looks good to me! Thank you for your time!

[nvnieuwk]

Something to keep in mind: there are still some bugs with the strict syntax which might break things here. I reported all issues I encountered so hopefully this should be fine once 26.04.0 releases

Not to be impatient, but is this going into a release soon?

[nvnieuwk]

There's no need to have it released right now since the strict syntax parser still contains some bugs. They should be fixed in the next edge version of Nextflow. I want to be sure first before releasing.

@lukfor is it okay if I ping you when it's ready for a release?

[lukfor]

Sure! You have a better sense of when the release is ready to ship. Thanks for taking care of it 🙏

Hoping to get the next edge release out tomorrow 🤞🏻
