bf598d6b8b
Adds new abstraction `Compiler` with methods `compileComponentAsync` and `compileComponentSync`. This is in preparation of deprecating `ComponentResolver`. `compileComponentSync` is able to compile components synchronously given all components either have an inline template or they have been compiled before. Also changes `TestComponentBuilder.createSync` to take a `Type` and use the new `compileComponentSync` method. Also supports overriding the component metadata even if the component has already been compiled. Also fixes #7084 in a better way. BREAKING CHANGE: `TestComponentBuilder.createSync` now takes a component type and throws if not all templates are either inlined are compiled before via `createAsync`. Closes #9594
