f52fd7a68b video: Don't use extra plane and componenent for tile format
Instead of using extra plane, we encode the number of tiles in x and y in the stride of
each planes (i.e. y_tiles << 16 | x_tiles) and introduce tile_mode, tile_width and
tile_height into GstVideoFormatInfo structure.

d899e6df5a video: rename NV12T -> NV12_64Z32
Is a bit more descriptive and allows us to add more tiled types
later.

We can just use the NV12 functions, the only difference is the
vertical subsampling.

c1a25d2ce7 video-format: fix interlaced 4:2:0 and 4:1:0 pack/unpack
For interlaced vertically subsampled images we need to combine alternating
chroma lines with alternating luma lines. That is line 0 and 2 are combined
with the first line of chroma samples and line 1 and 3 with the second line
of chroma samples.

a18c098f82 video: add option to unpack and truncate the range
Add an unpack option to specify what to do with the least significant bits of
the destination when the source format has less bits than the destination. By
default we will now copy the most significant bits of the source into the least
significant bits of the destination so that the full color range is represented.
Add an option to leave the extra destination bits 0, which may be faster and
could be compensated for in the element algorithm.

Use a separate variable to describe the amount of lines that will be used in
packing instead of abusing the h_sub variable. Some formats might have no
subsampling but need to operate on multipe lines.
