Inconsistency: `identity.clearAllCachedAuthTokens` API availability

[twschiller]

Description

• The identity.clearAllCachedAuthTokens endpoint is inconsistently supported across browsers. It looks like it might only be only available on Chrome?
• What's the intended behavior of the method? Is it only for use in clearing the Google-specific token in Chrome?
• It'd be good to get it added to MDN compatibility matrix, and for the MS Edge team to chime in on support

Documentation

• Chrome documentation
• MS Edge support list: makes no mention of of the API not being supported
• Firefox/MDN: not listed (and not supported by Firefox)
