7efd61fcf5 WindowSerer+LibGUI: Send multiple rects in invalidation/flush messages.
This patch moves to sending up to 32 rects at a time when coordinating the
painting between WindowServer and its clients. Rects are also merged into
a minimal DisjointRectSet on the server side before painting.

Interactive resize looks a lot better after this change, since we can
usually do all the repainting needed in one go.

5eedb22834 Sprinkle use of AK::Vector in various places.
Some of these are less helpful than others. Avoiding a bunch of mallocs
in the event loop wakeup code is definitely nice.

98784ad3cb WindowServer: Avoid overdraw by shattering dirty rects into unique shards.
The algorithm I came up with is O(n^2) but given the small numbers of rects
we're typically working with, it doesn't really matter. May need to revisit
this in the future if we find ourselves with a huge number of rects.
