[kacperzolkiewski]

Summary

Adds text alignment for Android
(Note: justify alignment is not natively supported for single spans on Android and will not work).

Test Plan

Run example app and play with textAlignment when different styles are toggled.
Check if paragraphs/lists with different textAlignment than auto are properly parsed and contain style="text-align:center|right" inside HTML

Why do we need to modify logic inside list styles?

[kacperzolkiewski]

The only behavior we modify in list styles is the handling of ZWS insertion and removal.
We need this because there may already be a ZWS present in a paragraph due to an applied alignment style. In that case, when applying a list style, we don't want to insert another ZWS, we should reuse the existing one.

Similarly, when removing a list style, we don't want to remove the ZWS if it is still needed by alignment style applied to that paragraph.

What's the plan for implementing justify on Android? There is no ready to use span for it, but we should find a different solution and bring justify support as it's pretty base alignement
