Reland "Implement AndroidBitmap_getDataSpace"
Originally reviewed in Ie05a45da32b2fd670abdae35626cd6548cfb102c
(and reverted in I0b06312f6583f766512cc771a35d3d735debcce1)
Bug: 135133301
Test: I7a5fcb726fba0c832bbb86a424d7534a7cfa35b6
This supplements AndroidBitmap_getInfo, allowing NDK clients to know how
to interpret the colors in an android.graphics.Bitmap.
Only build android_bitmap.cpp on Android so that it can rely on
libnativewindow (which is Android-only) for data_space.h
