  [Clang] [NFC] Update OptionalUnsigned ctor to only reject signed integers (#212321)

Currently, the `OptionalUnsigned(int) = delete;` constructor means that
constructing e.g. an `OptionalOrUnsigned<uint64_t>` from an `unsigned`
fails because overload resolution is ambiguous (because `unsigned` ->
`int` and `unsigned` -> `uint64_t` are both valid conversions). This
patch adds a constraint to make sure the deleted constructor only
catches signed integer types.

This is needed for #212319.
