Work around incorrect Skia gamma

Bug: 74408046
Test: Ic6acdc4a1a16840ec6ad9b13b4926c643d0f81ae

Skia incorrectly sets the gamma for LINEAR_EXTENDED_SRGB to 0 as a
misguided optimization attempt. As a result, a HARDWARE Bitmap which
natively has this color space does not match it properly. (Note that we
already catch an F16 Bitmap, above.) Add a workaround in
Bitmap.getColorSpace() to check for the color space explicitly.
