Provide more options for non-generic check evaluate functions

[WilcoFiers]

Adding these options will make it easier to configure these checks in custom rules:

• Label/duplicate-img-label
  • Options for parent selector
• Language/has-lang
  • Options for which attributes to look at
• Language/valid-lang
  • Options for which attributes to look at
• Navigation/region
  • Option for what elements are considered regions using a matcher
• Shared/avoid-inline-spacing
  • Option for inline spacing css props
• Tables/scope-value
  • Option for invalid values of scope

Other checks either already have options, they will be replaced with more general checks, or they will be configurable through commons.

QA: you'll need to look at each of the individual prs listed here to know what the options for each check is called.

Seeing the changes on all Options (Options.value) and instead normal methods, observed getter methods and call funtions. Please let me know is there any specific impacts on tests/test results.

1. duplicate-image-label - check verified with the test data - <div aria-label="Plain text"><img id="target" alt="Plain text"></div> , seeing the same results with old changes and new changes. As there is no impacts on results with the current changes.
2. has-land - check verified with the test data - <div id="target" foo="cats"></div>
   like wise..
