Updates for Firefox 127 beta / WebGL drawingBufferColorSpace

[Elchi3]

The @openwebdocs BCD collector project v10.10.6 found new features shipping in Firefox 127 beta which was released last week. Currently, the collector covers about 90% of BCD, so the following list might not be exhaustive. Also, if a feature is in Firefox Nightly only, it is not considered here.

With this PR, BCD considers the following 21 features as shipping in Firefox 127:

• api.Clipboard.read
• api.Clipboard.write
• api.ClipboardItem
• api.ClipboardItem.ClipboardItem
• api.ClipboardItem.getType
• api.ClipboardItem.presentationStyle
• api.ClipboardItem.supports_static
• api.ClipboardItem.types
• api.WebGL2RenderingContext.drawingBufferColorSpace
• api.WebGLRenderingContext.drawingBufferColorSpace
• css.types.image.gradient.repeating-radial-gradient.interpolation_color_space
• javascript.builtins.Set.difference
• javascript.builtins.Set.intersection
• javascript.builtins.Set.isDisjointFrom
• javascript.builtins.Set.isSubsetOf
• javascript.builtins.Set.isSupersetOf
• javascript.builtins.Set.symmetricDifference
• javascript.builtins.Set.union
• webextensions.api.declarativeNetRequest.getDynamicRules.filter
• webextensions.api.declarativeNetRequest.getSessionRules.filter
• webextensions.api.management.ExtensionInfo.installType

@hamishwillee and others manually submitted PRs for Firefox 127 last week which I reviewed and double checked against the OWD collector results. See

• FF127 base href forbids javascript and data URLs #23164
• FF127 clipboard enabled #23134
• FF127 TC39 Set methods supported #23089
• Add Firefox support for gradient colour spaces #23176
• Add filter to getDynamicRules and getSessionRules #23114
• install_type added to management API #23155

This means that this time the diff of this PR is small and only contains WebGL additions which weren't previously talked about by Hamish et al. The bug for that is https://bugzilla.mozilla.org/show_bug.cgi?id=1885491. r? @hamishwillee

Thanks very much @Elchi3 - FYI only, created mdn/content#33850 for tracking work that needs to be done. Won't become a priority until they confirm it is actually going to be released.
