net/http, net/http/internal/httpcommon: add httpcommon package
The golang.org/x/net/internal/httpcommon package is
a new package containing internal functions common to the
HTTP/2 and HTTP/3 implementations.
Update to golang.org/x/net@v0.35.1-0.
20250213222735-
884432780bfd,
which includes the httpcommon package.
Since net/http can't depend on a x/net/internal package,
add net/http/internal/httpcommon which bundles the x/net
package.
