Increase maximum gpu resources from 1024 to 4096

Increase maximum gpu resources from 1024 to 4096

Pictures with many drawn paths benefit from the increase of the
count. As an example, chalkboard testcase has ~2500 paths, tiger
has ~300.

Bigger objects, like textures, tend to be limited by the cache
byte limit, not item count.

Is the current limit determined with the skp db you guys have, or would
increasing it be possible?

We ran into a problem in the past with a large texture count, particularly
around gradient textures. Some device's driver got slow with a high texture
count. It was a long time back and since then we've started atlasing gradient
tables. So lgtm, we can always revert if perf.skia.com shows a problem. Note
that Chrome explicitly sets the cache limit after it creates a GrContext.
