Updates for Firefox 125 beta

[Elchi3]

The Open Web Docs BCD collector v10.10.2 found new features shipping in Firefox 125 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 40 features as shipping in Firefox 125:

• api.Element.ariaBrailleLabel
• api.Element.ariaBrailleRoleDescription
• api.ElementInternals.ariaBrailleLabel
• api.ElementInternals.ariaBrailleRoleDescription
• api.HTMLButtonElement.popoverTargetAction
• api.HTMLButtonElement.popoverTargetElement
• api.HTMLElement.beforetoggle_event
• api.HTMLElement.hidePopover
• api.HTMLElement.popover
• api.HTMLElement.showPopover
• api.HTMLElement.toggle_event
• api.HTMLElement.togglePopover
• api.HTMLElement.togglePopover.returns_boolean
• api.HTMLInputElement.popoverTargetAction
• api.HTMLInputElement.popoverTargetElement
• api.RTCDtlsTransport.iceTransport
• api.RTCIceTransport
• api.RTCIceTransport.gatheringState
• api.RTCIceTransport.gatheringstatechange_event
• api.RTCIceTransport.state
• api.RTCIceTransport.statechange_event
• api.SVGAElement.text
• css.properties.transform-box.content-box
• css.properties.transform-box.stroke-box
• css.selectors.backdrop.popover
• css.selectors.popover-open
• html.elements.button.popovertarget
• html.elements.button.popovertargetaction
• html.elements.input.popovertarget
• html.elements.input.popovertargetaction
• html.global_attributes.popover
• javascript.builtins.Intl.Segmenter
• javascript.builtins.Intl.Segmenter.Segmenter
• javascript.builtins.Intl.Segmenter.resolvedOptions
• javascript.builtins.Intl.Segmenter.segment
• javascript.builtins.Intl.Segmenter.supportedLocalesOf
• javascript.builtins.Intl.Segments
• javascript.builtins.Intl.Segments.containing
• javascript.builtins.Intl.Segments.@@iterator

Again, I hope this generated PR is useful to update BCD for the new Firefox 125 more easily and faster. If you have feedback, let me know!

@Elchi3 I've worked on the popover, RTC, JavaScript and WASM bits of this so happy to approve all that. The values for the CSS transform-box and backdrop make sense based on associated issues but I haven't any direct experience (@dletorey might comment).

UPshot, approving as correct for most and "very likely correct for the rest". You're welcome to merge if that is sufficient.
