cmd/go: export type State

Browse source 
Export the type `State` and add global variable `LoaderState` in
preparation for refactoring usage of other global variables in the
modload package.

This commit is part of the overall effort to eliminate global
modloader state.

[git-generate]
cd src/cmd/go/internal/modload
rf 'mv state State'
rf 'add State func NewState() *State { return &State{} }'
rf 'add init.go:/NewState/+0 var LoaderState = NewState()'
