Use CONFIG_INTERINTRA to properly separate interintra from the basic
ext_inter experiment.
When macro REDUCE_INTERINTRA_MODES is 1, only 4 ii modes are enabled
so as to reduce the complexity overhead.
(Right now the flag is off)

Also fix a mismatch for resizing with ext-refs enabled.

There are various preconditions which need to be true for it to
be valid to set cm->use_prev_frame_mvs = 1, including that the
sizes of this frame and cm->prev_frame must be equal.

With ext-refs enabled, we would sometimes decide to change
cm->prev_frame to point to the LAST_FRAME reference, without
re-checking the preconditions. If the LAST_FRAME was smaller
than the current frame, this could lead to reading garbage off the
end of its mv array, and eventually to an encode/decode mismatch.

We fix this by rewriting the preconditions as checks on
cm->prev_frame directly (rather than using cm->last_width and
cm->last_height), and by testing the preconditions after any
possible adjustment.

This should not affect the bitstream unless ext-refs is enabled,
but may affect the bitstream with ext-refs even if resizing is
not used.

This also avoids having 'bit_depth'/'bd' members whose presence
is decided by the preprocessor.

The goal is to simplify statements accessing the bitdepth value.
(instead of forcing them to also rely on the preprocessor to query
the member presence through #if CONFIG_HIGHBIDEPTH).

The frame superresolution experiment currently makes no use of the
features of the loop restoration experiment. While this is planned for
the future, there is no reason to continue having frame superresolution
depend on loop restoration for now.

Frame superresolution was made dependent by having every preproccesor if
containing its config flag also depend on the loop restoration config
flag. Those if's are modified to only check the frame superresolution
flag by this patch.

Stores the reconstructed luma pixels for each transform block inside a
prediction block. Rectangular transform blocks are supported.

As for RDO, after all the modes have been tested for luma, an extra
encoding is perform in order to store the reconstructed pixel values of
the best mode. These values are then used for RDO on the chromatic
planes.

The rate-distorsion impact of computing DC_PRED at the prediction block level
for chroma planes is rather small

Added 2 tile encoding modes:
TILE_NORMAL mode supports the large-scale tile coding up to 1024 x 1024
tiles;
TILE_VR mode supports the large-scale tile coding and also the decoding
of a single tile.

TILE_NORMAL mode allows the non-vr content to be encoded in multiple tiles
without using the coding tool that are designed for vr applications.
