compiler: support type args with mixed kinds

Type args can currently have only one type of kindInt, kindIdent,
kindString, or kindAny. The descriptions are checked against expected
type arg kinds, with kindAny meaning that anything is allowed (often
restricted with custom checks).

Concretely, it means that in a description as follows, arg1 and arg2
can each take a single kind of values.

    type[arg1, arg2]

This is limiting if we want arg1 to be able to take both an int or
flags. We thus need type args to support having mixed kinds. This
commit achieves this by turning the kind constants into bit flags.

This will be useful in a subsequent commit, but we can also already use
it for one existing type arg, the first of string types:

    string[literal_or_flags, size]

literal_or_flags changes from kindAny to kindIdent|kindString and we can
remove the custom check that used to enforce this.
