Ehsan Nasiri da4ae05638 Add command line options struct for the validator
The limit for the number of struct members is parameterized using
command line options.

Add --max-struct-depth command line option.
Add --max-switch-branches command line option.
Add --max-function-args command line option.
Add --max-control-flow-nesting-depth option.
Add --max-access-chain-indexes option.
