[Apps] Allow extra parameters to be passed to action execution (#25198)

* [Apps] Allow extra parameters to be passed to action execution

For actions, unlike queries, the user will be asked to fill in unmapped
parameters. This change allows the dashboard action execution to accept
incoming parameters without an "id" but with a "target". If that target
exists on the action, it will be accepted.

* Update doc string and validation message

* Review changes

Remove action-id from the execute endpoint, this will be looked up
through the dashcard.

Revert map-parameters and split parameters into an extra_parameters
value. extra_parameters are combined with the mapped parameters and
passed to execution.

* Fixing tests
