Combo boxes might be editable (Android accessibility)

A more comprehensive fix is coming here:
https://chromium-review.googlesource.com/c/chromium/src/+/642056

This is just a smaller patch in the meantime that fixes the
critical usability issue on Android - when a text field has a
role of combo box we're not treating it as editable text so
TalkBack doesn't support cursoring through it.

This affects the google.com search box.

Not a new regression, but requesting a merge to M62 since it impacts google.com and the Android accessibility team has requested we get this fix in as soon as possible.

I deliberately did a small, safe fix here that's easy to merge, and I'm following up with a larger refactoring to address the underlying issue on trunk.

Your change meets the bar and is auto-approved for M62. Please go ahead and merge the CL to branch 3202 manually. Please contact milestone owner if you have questions.

On latest M62: 62.0.3202.38 , it announces the typed character only, its doesn't speak "end of field". Thanks
