pdl: Add u64 or usize suffix to mask_bit output

We already handled the case where the generated integer literal is so
large that it doesn’t fit into the default i32 type. This was handled
by adding an explicit u64 suffix.

However, this produces invalid code if we use the u64 integer in an
expression where we actually expect an usize. We now take that into
account with an explicit suffix argument.

This was found during the integration with UWB.
