Adjust priority of linting filters if proprocessor directives conditions are met

Any filters list has its own installation preference/ideal like that AdGuard filters lists are expected to be installed on AdGuard products and uBO's uAssets filters on uBlock Origin.
However, to partly/silently/fully support installation on a 3rd-party adblocker platform, each filters list can use proprocessor directives condition (`!#if`) that can override `platform`/`syntax` value of pre-existing AGLint config file.

However, current beta (`4.0.0-beta.3`) does not adjust priority of linting filters with any proprocessor directives condition.

For example, the attached screenshot shows that AGLint ignores `!#if (ext_ublock)` and follows `platforms: adg_any`. Therefore, I can see an error.
