[BugFix][Android] Avoid null drawable invalidation for TextService images

- Pass the loaded inline image drawable to Drawable.Callback instead of invalidating with null.

- Handle TextService and null drawable invalidation in AndroidText by redrawing the host view directly.

- Verified with git diff --check and Android noasan debug build/install.
