LocalSite.ALL was typed as a Final[_LocalSiteConstants], which

worked fine in some cases, but didn't always match correctly. This is

because, depending on typing, passing a LocalSite.ALL as a

_LocalSiteConstants.ALL could be seen as passing a

_LocalSiteConstants as a _LocalSiteConstants.ALL, which clearly

doesn't match.
Now, LocalSite.ALL is a Final[Literal[_LocalSiteConstants.ALL]],

which helps it always match anything accepting _LocalSiteConstants.ALL

as a type.

Tested this against some in-progress code that was failing to

type correctly.
Checked existing usage of LocalSite.ALL being passed as an

AnyOrAllLocalSites, and found that it was still working as

expected.
