[SP 2025-09-01] Don't blur too many layersbanksia-dev

An application requesting lots and lots of blurs:
a. Enables pixel stealing by measuring how long it takes to perform a
blur across windows
b. Probably isn't very valid anyways.

So, just arbitrarily pick an upper bound for blur requests that a
display is allowed to manage (10), and disable everything else.
Arbitrarily, pick the 10 "front-most" blurs to be respected.
