slices,maps: delegate to go1.21 functions of the same name

This change replaces the body of almost every function in the package
with a call to its corresponding std function of the same name
and--assumedly--semantics.

If proposal golang/go#32816 is accepted, we will annotate each function
with a "//go:fix inline" comment so that automated tooling
such as golang.org/x/tools/internal/refactor/inline/analyzer
can automatically inline the wrappers.

(This CL is deemed to fix golang/go#70717 because it reduces maps.Clear
to the same status as all the other maps functions.)

Updates golang/go#32816
Updates golang/go#70815
Fixes   golang/go#70717

PkgGoDev

This subrepository holds experimental and deprecated (in the old directory) packages.

The idea for this subrepository originated as the pkg/exp directory of the main repository, but its presence there made it unavailable to users of the binary downloads of the Go installation. The subrepository has therefore been created to make it possible to go get these packages.

Warning: Packages here are experimental and unreliable. Some may one day be promoted to the main repository or other subrepository, or they may be modified arbitrarily or even disappear altogether.

In short, code in this subrepository is not subject to the Go 1 compatibility promise. (No subrepo is, but the promise is even more likely to be violated by go.exp than the others.)

Caveat emptor.
