Revert change to compatibility data for font-size-adjust in Chromium browsers (#5755)

* Revert "Fix Chromium versions for font-size-adjust (#4762)"

This reverts commit bc674e2a51cb0c3de4aea8a1cd7bce71bcd41dd2.

The Pull Request for bc674e2 was raised based on a comment stating that font-size-adjust was enabled by default in Chrome 54. I've not been able to find any evidence of this.

According to Chrome Platform Status [1], Chromium Issue 451346 [2], Can I Use [3] and manual testing [4], font-size-adjust is still (as of Chrome 80) behind a flag.

* Fix linting issues post revert

Based on the linter output, I've replaced `null` with `false`, and updated webview_android to `false` as there are no flags to enable.

Problems in 1 file:
✖ css/properties/font-size-adjust.json
  Versions – 1 error:
  → css.properties.font-size-adjust - This browser (webview_android) does not support flags, so support cannot be behind a flag for this feature.
  Real values – 2 errors:
  → css.properties.font-size-adjust - opera_android no longer accepts null as a value
  → css.properties.font-size-adjust - samsunginternet_android no longer accepts null as a value

* Chrome / Opera on Android mirror desktop for font-size-adjust

Based on feedback in the pull request [1], update Chrome Android and Opera Android to mirror their desktop counterparts for font-size-adjust (enabled, behind flags):

> I think this should mirror Chrome Desktop's data -- for a CSS feature like this, I'd be surprised if there were any differences between Desktop and Android.

* Remove unflagged support for font-size-adjust in Edge

Based on feedback in the pull request [1], remove flag-less support for font-size-adjust in Edge:

> The statement that reads just "version_added": "79" (without the flag) data should be removed, since Edge 79+ is Chrome-based. If Chrome doesn't have flagless support, Edge certainly won't!
