add `-ignore-capabilities` flag (#3984)

`-ignore-capabilities` flag allows ignoring capability incompatibilities/discontinuity errors/warnings. We still process capabilities (needed for stdlib).

Added to capability tests to ensure everything is working as intended. More will be added in the full stdlib capabilities implementation.
