Move interfaces defined by the WebGL spec to the `script/dom/webgl/ `module from `script/dom/`. `script/dom/webgl*.rs` -> `script/dom/webgl/` `script/dom/webgl_extensions` -> `script/dom/webgl/extensions` `script/dom/webgl_validations` -> `script/dom/webgl/validations` Testing: No changes, just a refactoring Fixes (partially): #38901 Signed-off-by: Andrei Volykhin <volykhin.andrei@huawei.com> Co-authored-by: Andrei Volykhin <volykhin.andrei@huawei.com>
