fingerprint: set dimlayer_hbm on finger up/down instead of auth/cancel
When dimlayer_hbm is enabled, HWC ends up disabling all color
transformations, including Night Light. Since we enable/disable
dimlayer_hbm on authenticate/cancel, this means that whenever the UDFPS
circle is present, Night Light ends up temporarily turning off. This is
especially not helpful on the lock screen, where the UDFPS circle is
active all the time.
Instead of turning on dimlayer_hbm during the entire time that the UDFPS
circle is showing, let's turn on dimlayer_hbm only when the user is
pressing down on the circle. In doing so, the color transformations will
be disabled for only when the user is touching the circle. We will still
disable dimlayer_hbm on cancel anyway, just in case that wasn't already
set to off by the time cancel() is called.
However, when enrolling a new fingerprint, the user is going to be
tapping on the UDFPS circle many, many times, and the user may prefer to
just keep dimlayer on for the entire duration. Add `isEnrolling` to
track that, and don't change dimlayer state while that is set to true.
