Fix behaviour of UseIdentityTableForNon420Chroma configuration parameter

See merge request jvet/VVCSoftware_VTM!1492

When UseIdentityTableForNon420Chroma is set to 1, the chroma QP mapping
table should be the identity table, i.e. QP_chroma = QP_luma. The encoded
table parameters are modified such as to generate the desired identity table.

Fix #976: IBC virtual buffer reset for large CUs

- Print a warning message when IntenalBitDepth is lower than InputBitDepth

Fix memory access issue in ALF SIMD code

See merge request jvet/VVCSoftware_VTM!1479

Issue flagged by address sanitizer. Happens when the picture height
is an integer multiple of the CTU height.
Memory buffer size is increased to avoid the issue.

Improved encoder configuration for Subpicture Level Information SEI

See merge request jvet/VVCSoftware_VTM!1476

- new pattern: create a class to collect all parameters  related to this SEI
- existing code can be refactored to use the same pattern for grouping to avoid endless assignments

Note: fixes executable flags for some unrelated config files
