Allow binding to ARIA attributes using property binding syntaxwithout theattr. prefix. For example,[aria-label]="expr" is now valid, and equivalent to[ariaLabel]="expr". Both examples bind to either a matching input or thearia-label HTML attribute, rather than theariaLabel DOM property.

Binding ARIA properties as attributes will ensure they are rendered correctly on the server, where the emulated DOM may not correctly reflect ARIA properties as attributes.

I would expect at least to have some new compliance tests (probably inpackages/compiler-cli/test/compliance/test_cases/r3_view_compiler_bindings).

Allow binding to ARIA attributes using property binding syntax _without_the `attr.` prefix. For example, `[aria-label]="expr"` is now valid, andequivalent to `[ariaLabel]="expr"`. Both examples bind to either amatching input or the `aria-label` HTML attribute, rather than the`ariaLabel` DOM property.Binding ARIA properties as attributes will ensure they are renderedcorrectly on the server, where the emulated DOM may not correctlyreflect ARIA properties as attributes.Reuse the DOM schema registry from the compiler to map property names intype check blocks.
