feat: omit resolved from registry dependencies

Implement `$disable-write-resolves` described in npm/rfcs#486.  I named
the option `omitLockfileRegistryResolved` but that can be changed later.

Put simply, this option causes npm to create lock files without a
`resolved` key for registry dependencies forcing npm to use the current
configured registry and resolve package tarball urls on install. This
fixes install errors when users change registries and the recorded
resolved url is incorrect.

This option causes slower installs because npm must fetch each packages
manifest to find the tarball url, but it's the most comprehensive
solution to this problem. Options like recording always the default
registry, or recording a special 'current registry' sigil will break if
registries host tarballs at different paths. For example
`${REGISTRY}/npm/-/npm-8.3.0.tgz` only works if all registries host
tarballs at `npm/-/npm-8.3.0.tgz`.
