lavfi/overlay: add enable expression
...
This expression is useful to enable/disable overlaying on the fly.
Note that this can't be easily done relying on the filtergraph structure,
since this implies caching issues or a null frame overlaying in the best
case, which is better avoided for performance and convenience reasons.

...
Add support for dynamic x, y expressions evaluation.
Also add support for an evaluation mode which allows to disable per-frame
evaluation, so that there is no speedloss in case the expression does not
depend on frame variables.
