These changes will fix executing javascript with any special characters, by making use of the evaluateJavascript function on Android 4.4+, and by properly escaping the URI on Android <4.4.

Fixes #19611 • Fixes #20365 • Fixes #9749 • Closes #19655 • Closes #12321

This PR supersedes #19655 by patching the same problem in all the places, and fixing it for Android <4.4 as well.

Test Plan:

The snack from #20365 should now work on Android as it does on iOS. That is, it should show "12" three times.

https://snack.expo.io/rkSxWhNVm

It can also be tested by instantiating a WebView with injectedJavaScript set to document.write('1')\ndocument.write('2') and observe that "12" is written in the WebView.

Release Notes:

[ANDROID] [BUGFIX] [WebView] - Properly escape JavaScript code

Seems like master fails CI for code style...

Rebased on master again but now the test is failing on something that seems related to iOS, and this PR only touches Android 🤔
