When INFO_FORMAT is not an image format there is no
need to make image WIDTH and HEIGHT mandatory.
2.x accepted that, 3.x raised an exception.
This is a partial fix: SRS is still mandatory because
fixing this would require a deeper refactoring and
I believe we can live with it, because SRS will be
required if filters are combined with geometry filters,
while passing a WIDTH/HEIGHT when we don't want an image
back is always useless.
A test was also added.
When an attribute table is set to a "Layer features" source, this
allows the underlying vector layer from which to source features
to be data defined.
(All existing table attributes (column settings) are left intact,
so setting a data defined table to a layer with different fields
will result in empty columns in the table.)

project dirtying for the lifetime of an object
Python code can then call:
project = QgsProject.instance()
with QgsProject.blockDirtying(project):
# do something
Use QgsProjectDirtyBlocker to prevent projects being marked as
dirty while creating a new project or while loading an existing
project -- avoids the titlebar temporarily showing the project
state as unsaved while it is being loaded.
This allows the project home path (which is used by the browser
to create the 'Project Home' item) to be set by users for a
project, instead of always matching the location where the project
is saved.
This allows users to set the project home to a folder which contains
data and other content, and is especially useful for organisations
where qgis projects are not stored in the root folder of a organisational
'project'.
Project home paths can also be set to relative paths, in which
case they will be relative to the project saved location.
The path can be set through the Project Properties dialog, or
by right-clicking on the Project Home browser item and
selecting 'set project home'

- Switch to flags instead of boolean argument
- Move logic for layer validity to canRunUsingLayer
- Add unit test
Also remove settings flag to hide duplicate features action
