Clean cherrypick into m33.

Bug: 13083442

Original description:

[Android WebView] Allow embedders to override text from scaling by
system font scale.

Relaxes the use of system font scale. Before this patch,
we would override the value passed to AwSettings.setTextZoom to take
into account system font scale. Now, if an app does not invoke
setTextZoom then we'll respect the system font scale. However if an
embedder then later invokes setTextZoom, we'll honor their value without
applying any scale.
