Added support for lilting provided files by paths

[dshikulin-mwb]

• Fixed "Unknown option '--target'". Option was passed to swiftlint tool even after extracting that option to determine targets' paths.
  • swiftlint tool doesn't support '--target' option, only command plugin does.
  • '--target' is passed by Xcode when you use GUI to run plugin command
    (see SwiftLintCommandPlugin Unknown option '--target' realm/SwiftLint#5603)
• Backwards compatibility
  • pass arguments without defining targets to run linting on all targets with passed arguments.
  • pass arguments and '--target' option to lint provided targets with provided arguments.
• New: pass arguments and paths without '--target' option to run linting only on these paths with passed arguments.

Sorry, created it by accident, you can delete it.
I plan to propose same to main repository.

@dshikulin-mwb Are you still planning on proposing this to the main repository? 🙂 We're currently running into the issue where the --target option is passed to swiftlint by the SwiftLintCommandPlugin.

[dshikulin-mwb]

@JayShortway Yep, will probably suggest these changes next week to main repo.

[JayShortway]

@dshikulin-mwb Alright, thank you! Looking forward to it.

@JayShortway
It was not a week, but the PR was opened :)

Probably the fixes that you were waiting for were already fixed in realm/SwiftLint@c784adc

In case if some one is interested in using CommandPlugin as CLI to lint only several given files, here is the PR:
realm/SwiftLint#5879

@dshikulin-mwb Haha no worries! I'm glad it's up 😄

Thanks for pointing me to realm/SwiftLint@c784adc. That indeed seems to be what we need.
