Previously, when `ngcc` was called with `compileAllFormats === false`
(i.e. how `@angular/cli` calls it), it would not attempt to process
more properties, once the first was successfully processed. However, it
_would_ continue looping over them and perform some unnecessary
operations, such as:
- Determining the format each property maps to (which can be an
expensive operation for some properties mapping to either UMD or
CommonJS).
- Checking whether each property has been processed (which involves
checking whether any property has been processed with a different
version of `ngcc` each time).
- Potentially marking properties as processed (which involves a
file-write operation).
This commit avoids the unnecessary operations by entirely skipping
subsequent properties, once the first one has been successfully
processed. While this theoretically improves performance, it is not
expected to have any noticeable impact in practice, since the list of
`propertiesToConsider` is typically small and the most expensive
operation (marking a property as processed) has low likelihood of
happening (plus these operations are a tiny fraction of `ngcc`'s work).
