Attachment: WIP: Bug 1868482 - reuse capabilities to save time for not querying capabilities again.

Querying capabilities can be time consuming, because that is depend on
the implementation of external library. If we already query the
capabilities for the same key system before, we should reuse the result.

Attachment: Bug 1868482 - part2 : cached capabilities in the MFCDM process.

We should always keep cached capabilities in the MFCDM process so that
we won't need to regenerate capabilities when asking that from different
content processes.

Depends on D205392
