script/verify_flags: make script_verify_flags type safe

Browse Source 
`using script_verify_flags = uint32_t` allows implicit conversion to
and from int, so replace it with a class to have the compiler ensure we
use the correct type. Provide from_int and as_int to allow for explicit
conversions when desired.

Introduces the type `script_verify_flag_name` for the individual flag
name enumeration.
