libcamera: camera_sensor: Reference test pattern modes by enum type

The CameraSensor stores TestPatternModes as an int32_t. This prevents
the compiler from verifying the usage against the defined enum types.

Fix references to the TestPatternMode to store the value as the
TestPatternModeEnum type which is defined by the control generator.
