cmd/compile/internal/types2: use an identifier map rather than isubst for recv type params

This is a port of CL 354643 from go/types to types2 with adjustments:
- use of syntax rather than go/ast package as needed
- adjustments due to the different code for type parameter declarations
- rename of Checker.rparamMap to Checker.recvTParamMap, which seems clearer
