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
This fix prevented waiting for child components even if the cycle was only introduced via the `directives` array, i.e. without actually having a cycle. This easily causes issues for applications that have one shared list of directives for all components.
This reverts commit 3d5bb23184.
Closes#9647
Fix how the compiler checks for recursive components by also considering
component descendants. Previously, it only checked if the current
component was evaluated previously. This failed in certain cases of
mutually recursive components, causing `createAsync` in tests to not
resolve.
