While many processing algorithms support data defined parameter values, these were not possible to specify when using the qgis_process tool (or when representing algorithm settings as JSON or qgis_process commands)
This PR adds new syntax to allow specifying data defined parameter values when running qgis_process, and ensures that all the helper functions for copying settings as JSON/qgis_process commands correctly handle data defined values.
Fixes #50482
