Support more dataspaces in DataSpaceToColorSpace

Bug: 135133301
Test: ?

Create an SkColorSpace for HAL_DATASPACE_TRANSFER_ST2084 and
HAL_DATASPACE_TRANSFER_SMPTE_170M. This allows converting
ADATASPACE_BT709, ADATASPACE_BT2020, and ADATASPACE_BT709 into
SkColorSpaces. In addition, treat HAL_DATASPACE_DCI_P3 (aka
HAL_DATASPACE_DCI_P3) specially, because its gamut does not match
SkNamedGamut::kSRGB.

This will allow Ia8ba4c17b517a05b664c6e317e235836473fd7f6 to use
DataSpaceToColorSpace, rather than its own, slightly different version.
