Description

Consider pulling in some options from Chromium's Accessibility settings page; filed this issue after speaking briefly to @rebron.

Steps to Reproduce

1. load chrome://settings/accessibility in Chrome/Chromium
2. note the available Accessibility options
3. load brave://settings/ in Brave
4. note the lack of available Accessibility options

Actual result:

We are missing the following:

• Live Caption
• Caption preferences
• Show a quick highlight on the focused object
• Navigate pages with a text cursor
• Add accessibility features

Live Caption -- as well as a few others -- are available, instead, as feature flags:

Expected result:

Pull in everything except "Live Caption" (for now) and "Add accessibility features". Move 'Pressing Tab on a webpage highlights links as well as form fields' from 'Appearance' section to the new Accessibility section

Live Caption and associated settings downloads files from Google, so not sure if we want that, and if so, if we want to proxy that?

Reproduces how often:

To this day the accessibility section is not existent in Brave's settings. This must change. Brave must incorporate more accessibility in the very least to have feature parity with Chromium.
