[IMPR] Add support to apply/ignore precompilers for certain feature files

[szikszail]

Summary

This feature would enable controlling per feature file, which precompilers are applied to the feature file.

Use cases

1. By default, all precompilers are applied (if, in general, the precompiler should be applied) to all feature files or if @gpc_apply(all) is set to the feature
2. If @gpc_apply(<name>) is set ( can be the name of the precompiler w/ or w/o the gpc- prefix) the given precompiler(s) are applied
3. If @gpc_ignore(<name>) is set ( can be the name of the precompiler w/ or w/o the gpc- prefix) the given precompiler(s) are not applied

Questions/To decide

1. Precedence: if ignore is set, applying for the same won't resolve it, does the order count
2. How to handle custom precompilers
