This change disables the FaceSettings Confirmation setting if a
sensor is convenience. This is due to the fact that convenience strength
sensors can't be used by BiometricPrompt (so this setting has no
effect.)
Test: Verified this setting shows depending on whether or not the sensor
is convenience or not.

Sometimes Settings Search show the items that are not supported by
the hardware. e.g. FaceLock.
Add log to check the HW status when the problem occurred.
