Load Int128 and UInt128 from a HUGEINT and UHUGEINT vector without a conversion

StorageType of the two columns is Int128 and UInt128, their default types,
where it was the DuckDB structs: the vector holds the 16 bytes of an Int128 on a
little-endian machine. ReadValidValue<Int128> then compares the type and loads
the value (vmovups, unaligned), for GetFieldValue, nullable reads, list items,
map keys and values, struct fields and function inputs. A read of the DuckDB
structs, which lose the fast path, is taken from the vector in GetValidValue, so
it is not boxed through the base class.

Read in the Tier 1 listing of .NET 10.0.14: ReadValidValue<Int128> is inlined
into GetFieldValue<Int128>; on .NET 8 it stays a call. Not measured.

2.0 item 9 (#370).
