All these overrides are temporary while generics development is in progress.

A few methods in time use generics to allow string or []byte to be used for formatting and parsing. To make these work I copied the method that needed to be temporarily replaced, then changed the generic parameter to any. The only complication is that one of these methods returns a generic type, meaning anything calling it has to have the value cast and thus overwritten too.

This is part of #1270. After these changes (and removing var _ = &Pointer[int]{} from sync/atomic/type.go:40) running go1.20.14 install -v && gopherjs build -v net/http results in:

go1.20.14/src/os/file_unix.go:119:1: gopherjs: //go:linkname can not insert local implementation into an external package "net"
../../../../../sdk/go1.20.14/src/os/proc.go:75:21: too many arguments in call to runtime_beforeExit
