What is the current behavior?

On Android API 22, setting large values for width or height in ImageAssetOptions causes the app to crash with "bitmap size exceeds 32 bits" (see #6289).

What is the new behavior?

This change caps the bitmap dimensions to 2048x2048 in imagepicker.android.ts to prevent bitmap overflow and crashes on API 22. The cap is applied regardless of user-supplied dimensions.
