Summary: Introduces the <a> element within the MathML namespace exposed via the new MathMLAnchorElement WebIDL interface (which inherits from MathMLElement and includes HyperlinkElementUtils). This feature aligns MathML hyperlink capabilities with HTMLAnchorElement and SVGAElement to ensure consistent link handling, styling, and privacy mitigation across HTML, SVG, and MathML. Linking in mathematical expressions allows authors to link specific terms, variables, or formulas to external references or definitions.

And we have tests for them. This feature also needs to update sanitizer spec and the default configurations in the sanitizer api.
