Auto merge of #24176 - jdm:no-gleam, r=asajeffrey

Replace use of gleam in webgl with sparkle.

Rely on https://github.com/servo/sparkle for the GL bindings required to implement Servo's WebGL stack. This does not touch the GL usage in the compositor or webrender, which continue to rely on https://github.com/servo/gleam. This means that any breaking changes to the public GL bindings interface (such as required by https://github.com/servo/servo/pull/24111) only require updating rust-offscreen-rendering-context and rust-webvr, rather than many other crates that are out of our direct control.
