feat: deprecate axe.imports and upgrade to css-selector-parser 3

[dependabot]

Because css-selector-parser 3.0 has changed its API completely we're unable to maintain full support for axe.imports.CssSelectorParser. As best we can tell this isn't used. axe.import is not a documented feature of axe-core, but just in case this PR adds a class that wraps css-selector-parser's createParser method.

Bumps css-selector-parser from 1.4.1 to 3.0.2.

Shouldn't update the casing of CSS otherwise this is a breaking change

Suggested change

	export { CSSSelectorParser, doT, emojiRegexText, memoize, Color as Colorjs };
	export { CssSelectorParser, doT, emojiRegexText, memoize, Color as Colorjs };

[straker]

This class isn't a 1:1 back compatible wrapper. The return of CssSelectorParser was a class, but the class also had additional functions that were used to configure the parser (registerSelectorPseudos, registerNestingOperators, etc.). In order to fully be back compatible, this class would need to implement those functions and probably then call createParser in the parse function with all the settings the user has set using the configuration functions.

[straker]

This changed the export to a named export so you'll also need to update the import in matches.

[dependabot]

A newer version of css-selector-parser exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.
