This enum can be used in the QgsProcessingUtils::mapLayerFromString()
and parameterAsPointCloudLayer() calls to control layer loading, e.g.
skipping index generation or not applying default style, etc.
This change adds a new "feature filter" option alongside the
existing feature limit and invalid geometry handling options
available for all vector inputs to processing layers.
It allows users to enter an expression to subset the layer dynamically
when running the tool, avoiding the need for separate steps to
set layer filters or create layer subsets.

to a single string
We need this to allow processing inputs to load non gdal/ogr/mdal sources, such
as being able to directly read postgis layers without loading them into a project first
A few releases ago a bug fix was implemented which forced conversions
of multi-layer sources. This was a valid bug fix, but the consequence
was that any algorithm using this api with a source file containing
multiple layers (e.g. gpkg) performed a complete copy of the target
layer to a new file, severely impacting performance.
This commit adds new API to retrieve a compatible layer path in the
case when an algorithm CAN correctly handle specific target layer names.
In this case, the forced copy of the source layer is avoided when
using multi-layer inputs like geopackage.
output format
This setting is still used and required in some circumstances, e.g.
it is used as the default selection in outputs file pickers when
the previously used format is not valid.
