[HWUI] Update Ganesh includes to specify new location

Upstream Skia changes I7269acfae5c26518c2a61930a8af9584682751cd and
Ibc927d0ae66a05546957300090a651614e720fad are moving Ganesh headers into
Skia's include/gpu/ganesh/ directory. Android's current includes are
relying on temporary shims which will soon be removed.

Note: I also sorted some includes to try and calm the chaos a tiny bit,
but didn't go out of my way to update all non-Ganesh Skia includes.

clang-format decided to further re-arrange things, so I'm hoping this
doesn't make future merge conflicts too painful.

Bug: 40044159
Test: builds after locally deleting Skia's temporary shims
Flag: EXEMPT refactor
