Updates for Firefox 128 beta

[Elchi3]

The @openwebdocs BCD collector project v10.10.7 found new features shipping in Firefox 128 beta which was released yesterday. 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 37 features as shipping in Firefox 128:

• api.Blob.bytes
• api.CSS.registerProperty_static
• api.CSSPropertyRule
• api.CSSPropertyRule.inherits
• api.CSSPropertyRule.initialValue
• api.CSSPropertyRule.name
• api.CSSPropertyRule.syntax

FWIW:

• all the javascript.builtins.xxx changes are good. Docs work for that in [JS] Ship Resizable and growable ArrayBuffers content#33983
• RTCRtpReceiver changes are good. Docs for that in [WebAPI] RTCRtpParameters.codecs aren't populated content#33988
• RTCRtpSender changes aren't "obvious" in the code - i.e. the method already existed from https://bugzilla.mozilla.org/show_bug.cgi?id=1401592#c49 - but the object returned would not have had codecs, because that was not present. So I think this "falls out" of the other changes and makes perfect sense.
• `RTCRtpTransciever changes are good. Docs for that in [WebAPI] Implement RTCRtpTransceiver.setCodecPreferences() content#33981
• api.MediaKeys.getStatusForPolicy() change good - Docs in [Web API] ship MediaKey::getStatusForPolicy() content#33980
• api.Blob.bytes - [WebAPI] Implement bytes() method on Blob for reading bytes into a Uint8Array content#33991
• api.PushMessageData.bytes - [WebAPI] PushMessageData: Add bytes() method for reading bytes into a Uint8Array content#33990
• api.HTMLMediaElement.seekToNextFrame (removal) [WebAPI] Remove HTMLMediaElement::seekToNextFrame content#33986
• [CSS] Let css-properties-values-api ride the trains content#33993 I think all of these api.CSS.registerProperty_static, api.CSSPropertyRule, api.CSSPropertyRule.inherits, api.CSSPropertyRule.initialValue, api.CSSPropertyRule.name, api.CSSPropertyRule.syntax, layout.css.properties-and-values.enabled - we need to confirm by searching on layout.css.properties-and-values.enabled
• [WebAPI] Implement Request/Response .bytes() method content#33984 for api.Request.bytes, api.Response.bytes
• css.types.calc.color_component - [CSS] Enable relative color syntax on stable. content#33985
  css.properties.content.alt_text - [CSS] Enable alternative text for 'content' property by default content#33992

MDN Needs to add tracking items for:

• https://bugzilla.mozilla.org/show_bug.cgi?id=1890428 HTMLTemplateElement.shadowRootSerializable, (pref dom.webcomponents.shadowdom.declarative.enabled) api.Element.getHTML(), api.ShadowRoot.getHTML, api.ShadowRoot.serializable - done in [Web API] Implement Declarative ShadowDOM serialization content#34302
• webextensions.api.declarativeNetRequest.getDisabledRuleIds - webextensions.api.declarativeNetRequest.updateStaticRules

Dont know about these:

css.at-rules.property
css.at-rules.property.inherits
css.at-rules.property.initial-value
css.at-rules.property.syntax
