Revert "👹 Add adaptable homescreen shortcuts for maskable icons."

This reverts commit ff026011.

Reason for revert: AddToHomescreen tests failing on Android CFI

https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Android%20CFI/3851

JNI ERROR (app bug): expected jboolean (0/1) but got value of 255 as argument 2 to void org.chromium.chrome.browser.webapps.AddToHomescreenManager.onIconAvailable(android.graphics.Bitmap, boolean)

Original change's description:
> 👹 Add adaptable homescreen shortcuts for maskable icons.
> 
> The Add to Homescreen feature will now consider "maskable" icons from
> the web app manifest [1]. If a maskable icon is present and we are on
> an Android O+ device, turn that "maskable" icon into an Android Adaptive
> icon [2].
> 
> The icon is scaled to ensure that the safe zone is preserved [3].
> 
> [1]: https://w3c.github.io/manifest/#purpose-member
> [2]: https://developer.android.com/guide/practices/ui_guidelines/icon_design_adaptive
> [3]: https://github.com/w3c/manifest/issues/555#issuecomment-404097653
