Older versions of Go don't format comments, so committing this as
a separate commit, so that we can already make these changes before
we upgrade to Go 1.19.

Simplify some of the logic, and add documentation about the package,
as well as warnings that this package should not be used as a general-
purpose utility.

pkg/urlutil (despite its poorly chosen name) is not really intended as a generic
utility to handle URLs, and should only be used by the builder to handle (remote)
build contexts.
- IsURL() only does a very rudimentary check for http(s):// prefixes, without any
other validation, but due to its name may give incorrect expectations.
- IsGitURL() is written specifically with docker build remote git contexts in
mind, and has handling for backward-compatibility, where strings that are
not URLs, but start with "github.com/" are accepted.
Because of the above, this patch:
- moves the package inside builder/remotecontext, close to where it's intended
to be used (ideally this would be part of build/remotecontext itself, but this
package imports many other dependencies, which would introduce those as extra
dependencies in the CLI).
- deprecates pkg/urlutil, but adds aliases as there are some external consumers.
