Kévin Dietrich fab51c3e35 Alembic: support camera and visibility animation via FCurves

This adds support to import animations on the various camera properties
and on object visibilities via FCurves for non-sequence Alembic files.

This adds a single routine `create_keyframes` to create FCurves for all
objects which need some for the entire duration of the animation in the
archive.

The FCurves creation and key frame addition are done via some newly
added `FCurveCreationHelper` objects which are created and gathered
during object creation if need be.

For camera data animation, as Alembic does not separate the various
properties into separate sample arrays, we initially create FCurves for
all properties and remove the ones which were unnecessary at the end.
