Auto merge of #20884 - jdm:more-limits, r=avadacatavra

Don't forward GL parameter gets for constant limits.

This avoids IPC traffic for unchanging constants that are determined when the GL context is created. These changes require https://github.com/emilio/rust-offscreen-rendering-context/pull/123.
