DO NOT MERGE Camera: Enable session parameter handling for Rotate&Crop

Service managed settings like Rotate&Crop are overridden just
before they are sent to camera provider. The session update
logic runs prior to that so it cannot detect any modifications
for keys advertised as session parameters by CameraHal.
Refactor the parameter override logic so it can be triggered
before the request thread starts processing the requests.
Additionally consolidate the specific override logic so it
can be re-used by the parameter session filter during
stream configuration.
Specifically for Rotate&Crop incoming AUTO session
values will be overridden accordingly.
In case 'mOverrideToPortrait' is enabled, the Rotate&Crop
session parameter value will always include the configured
override.

Bug: 272528553
Test: Camera CTS,
Manual using Camera2Basic on CF with R&C set
to AUTO. The overridden filtered R&C session value is
NONE.
