Add speech API

[autonome]

• confirmed not already in progress
• moved files
• updated filename if needed (eg remove "TC39-" or s/webdriver2/webdriver/)
• removed draft date
• determined name
• added description (triangulated from mdn, spec, caniuse)
• added entry point
• verified baselines
• checked api list against mdn list
• added to a group or not
• determined whether the feature should be split
• looked for other related draft features that could be included
• what else?

Filename

Philip did the synth part already and named it speech-synthesis.yml.

The remaining bits are the SpeechGrammar and SpeechRecognition APIs, so i'll split this up into three files for now, along the speech-*.yml pattern.

Name

Again, will follow the pattern already started w/ the synth api.

Group

There's already separate groups made, which seems odd. Feels like if we're coalescing 14k pieces of web platform surface area into 2-3k features, all of this would be the Web Speech API, which is how developers, spec authors and MDN all seem to think about it. But Philip kicked this one off and is one of the spec authors so, I'll leave it as is for now.

Splits/Merges

See above, I suspect we group this into a single feature later.

@ddbeck any idea why SpeechGrammar is in BCD but not mapping here?

I'm sorry, but I'm not 100% sure what this means. Are you asking why the computed status is unsupported but the compat data shows some kind of support (e.g., https://developer.mozilla.org/en-US/docs/Web/API/SpeechGrammar#browser_compatibility) it's because of prefixes and runtime flags, which don't count toward a Baseline status.

[autonome]

bah, i had commands that searched features/draft/spec but not features/draft so missed the file there.

PR on hold indefinitely, if/when speech apis get unprefixed.

[ddbeck]

It's OK to have features that aren't Baseline in the feature set (we just need to make sure that it makes sense when we do!), if you still want to move ahead on this.

[autonome]

Ok, i think this is ready now. SpeechGrammar is all prefixed everywhere , looks like.

Pre-review, overall looks good!

[autonome]

Thanks for review @jamesnw, fixes made, ready for @ddbeck

[ddbeck]

Getting pretty close. One big suggestion (merging a feature) and some nits.

[ddbeck]

Thank you!
