Rename SlimmingPaintV2 to CompositeAfterPaint

The name "SlimmingPaintV2" has led to confusion about what exactly is in
"v2". This renames the in-development feature to "CompositeAfterPaint".
Tasks left to do:
1) Remove the --enable-slimming-paint-v2 flag
2) Remove the SlimmingPaintV2 runtime enabled feature
3) Move the virtual tests from virtual/spv2 to virtual/composite-after-paint
4) Move the flag-specific expectations to enable-features=CompositeAfterPaint

{
  name: "CompositeAfterPaint",
  implied_by: ["SlimmingPaintV2"],
},
git cl format

I then manually cleaned up some instances of "composite after paint" being
"CompositeAfterPaint" as well as some grammar.
