fbad91165c Add feature source test for QgsVectorLayerCache 
While it's not a QgsFeatureSource subclass (yet), it behaves
just like one so when can run the feature source conformance
test suite over it.

Fix a few minor issues identified by the test suite, and one
potential crash (requesting an invalid id from a cache iterator
crashes qgis)

64a86e3d6c Add an explicit argument to set QgsGeometryValidator method 
Previously this was always read from settings when using
QgsGeometryValidator. It's now an explicit argument
when constructing QgsGeometryValidator or calling the
static validation methods, allowing choice of internal/GEOS
validation methods.

Helps remove more QgsSettings use from core.

72be86dc61 Only accept QgsPropertys in QgsProcessingFeatureSourceDefinition/ 
QgsProcessingFeatureSink, not all QVariant types

Only strings/QgsPropertys are valid anyway, so instead of strings
use static properties. This makes it clearer what possible
values are permitted for the underlying source/sink definition.

ed09a8a727 Create class for encapsulating settings relating to a feature source 
input to a processing algorithm.

This allows parameter inputs to encapsulate extra information
relating to a feature source input, such as whether only
selected features from the source layer should be used.

b6fb41d4ee [processing] Don't use vector layers directly as feature sources 
Instead, parameters evaluate to QgsFeatureSource, which are
used for retrieving features, feature count, crs, wkb type,
etc.

This abstracts away the actual feature source, so that
algorithms may potentially operate from non-layer
feature sources.

It also helps remove the need for specialised QgsProcessingUtils
methods like getFeatures, featureCount, and createSpatialIndex.
Instead the standard API methods using QgsFeatureSources can
be used instead.

005a08ead9 Create class for encapsulating settings relating to a feature sink 
input to a processing algorithm.

This allows parameter inputs to encapsulate extra information
relating to a feature sink input, such as destination file
encoding and whether the sink layer should be loaded into
the project on completion
