[VCWG-G144/G133] bitstream conformance for bitstreams contains SWICTH frames

[jkeui]

VCWG-133 and 144 (resolve #5418)
1) add requirement checks to encoder and decoder
1-1) refMVbank=0
1-2) allow_intrabc=0, allow_bawp=0 if refMVbank=0 after a switch frame
1-3) oplf=0 RefineMV=0
2) add a CLI option(--sframe-conformance-option) to apply one of the requirement(constraint) to the encoder
--sframe-conformance-option=0 : (default) --enable-refmvbank=0 + BAWP is disabled after a switch frame
--sframe-conformance-option=1 : intraBC is disabled after a switch frame if --enable-refmvbank=1 + BAWP is disalbed after a switch frame
--sframe-conformance-option=2 : --enable-opfl-refine=0 --enable-refinemv=0

Also check git@github.com:mabenjak/avm.git(Martin Benjak)'s switch_DVMR_experiments branch (commits 47a8c2c, 31b14ea)

This branch also includes three other encoder items which can be disabled.

1. 2d85428 - Removing the encoder-side limitation for restricted switch frames
2. 4140cf6 - sframe-replace-kf : changes the coding structure when switch frames are used
3. 97146c6 - sframe-refresh-all : the switch frame refreshes all RPL slots or just one

[jkeui]

1. Note that if a non-restricted switch frame is used, reference frames are all refreshed regardless of sframe-refresh-all
2. Also note sframe_mode is set as 0 for multi-layer tests since "non-restricted switch frame + sframe-refresh-all=0" may bring inevitable decoder crash. With 1, "non-restricted switch frame + sframe-refresh-all=0" is prevented.
3. These are all encoder settings.

The added checks assumes a bitstream only contains a single layer with a switch.

There are currently no restrictions in the specification which force this.

In particular, this code would not match the specification if:

1. Using multiple extended layers (perhaps the new risk variables should be added to av2_store_xlayer_context and av2_restore_xlayer_context?)
2. Using multiple embedded or temporal layers (perhaps the new risk variables should be stored per embedded and temporal layer?)

I have updated the code.
I also added a few more things.

1. TLayerPresenceMap[][][]
2. The scope of the restriction for OLK at the decoder : it ends at the regular TU after the OLK TU.
