WebKit mappings are not correct for style-based roles: strong, emphasis, maybe more…

There are number of AXSubroles listed that don't match the implementation: AXStrongStyleGroup, AXEmphasisStyleGroup, etc.

Looks like @joanmarie made the change in WebKit but it was immediately reverted, due to breakage. So it was only in a single nightly build, as far as I can tell. WebKit/WebKit@8095dc1

FWIW, I'm still of the opinion that <strong> and <em> should map to generic, not new stylistic ARIA roles.

<code> and some others seem reasonable to have a role. See discussion in w3c/html-aam#373

Regardless of whether we keep or ditch the strong role, I think the mapping for <strong> and <b> would still be:

AXRole: AXGroup
AXRole: <nil>
Expose the text style as Bold.

Ditto for the new emphasis style role:

AXRole: AXGroup
AXRole: <nil>
Expose the text style as Italic.

Which WebKit already does, so this fix can probably proceed regardless of the other discussion about generic roles. I'll wait a while for @joanmarie or others to comment before posting a PR.
