drm_hwcomposer: Store pixel_stride in the hwc_drm_bo
The new GraphicBufferMapper ImportBuffer takes a pixel_stride
as an argument, so we need to caluclate that and store it in
the hwc_drm_bo at import so we can use it here.
I'd still welcome better ideas to calculate pixel_stride for
generic drm importer.

v2:
* Utilized pixel stride values already in some gralloc handle
implementations
* Fixed embarasing bit/byte math snafu (preserving bits per
pixel since YUV conversions using bytes doesn't seem sane)
- Extra review still would be appreciated here!
v3:
* Renamed to use Drm... instead of DRM...
