feat: add generator skip option for table columns

[galexrt]

This is a quick implementation of having a skip option for table columns/fields in the generator for the feature request I created #435.
This might not be optimal but the easiest way I found to implement this feature.

Resolves #435

Hi @galexrt,
Yeah, it makes sense to have such a feature.
Not sure if it is intentional, with this change you're skipping only SQL builder columns, not model fields.
Could you also add a test here:

jet/tests/postgres/generator_template_test.go

Line 451 in f9ed359

[galexrt]

I have added a test and due to it being easier to handle skipped fields for the column-list, I had added a template function columnList to render the list via strings.Join.

Please let me know if the combined test for model and sql builder is okay or should be split.
