Asset Browser: Filter options for specific ID types

Adds a filter popup to the header that allows specifiying which data-block
types to show. The menu automatically reflects all supported ID types, so it
shows a checkbox for materials, worlds and actions currently by default, and
all ID types with the "Extended Asset Browser" experimental feature enabled.
