Remove lockpattern utils construction...

where possible. By invoking the constructor, we are not reusing the
cache that will mitigate binder calls for reading state. There is an
instance of LockPatternUtils that is injectable via dagger. Some
classes, however, cannot inject this. (i.e. view, service, or static
method). I've removed the instances where I could to hopefully mitigate
binder calls and jank.

Fixes: 268192609
Test: Check to see if bouncer works properly mostly.
