Instantiate new Unicode::Collate::Locale object with some extra reporting checks.
We need this also so that we can chain some things during sorting object construction.
Without an object, we would need to call a regular subroutine but due to the special
semantics of Schwartzian transforms, we need to chain all sorting elements so that they return
a boolean value (see Biber.pm). This is much tidier with Foo->new()->change()->cmp than
with something messy like "my $uc = create_uc_object; $uc->change()->cmp()" etc.
