GPU: Instrument AsyncTexImage2D and TexImage2D for telemetry.

GPU: Instrument AsyncTexImage2D and TexImage2D for telemetry.

This makes the total_texture_upload and total_texture_upload_time results
from telemetry consistent when run with and without impl-side painting.

Without this change, AsyncTexImage2Ds aren't accounted for in the telemetry
results. On many of the tests (like top_25.json), AsyncTexImage2D is the vast
majority of tex upload.

lgtm, we should probably follow up with a change that makes normal sync
TexImage2D also report upload stats.

Yeah. I did some digging and without impl-paint, we prefer glTexStorage2D and
glTexSubImage2D, which is why the numbers matched running w/ and w/o impl-paint.
I've now instrumented glTexImage2D to cover platforms where we don't use
glTexStorage2D.
