rta: store real types in live_cast_type

The separate compiler need to distinguish if the target is nullable or not.
So do not un-nullable cast types.

rta_metrics.nit is also updated to deal with the change of the static
type of the attribute.

nitg-g is also modified to use the new correct the RTA information
(this remove a workaround)

nitg-s: use table_size instead of resolution_table to check live types

A future commit will remove resolution_table on live type that does not
need one (no formal types)

nitg-s: compile_type_to_c generate partial tables for dead types

If a type is not live (instantiated) or not cast-live (someone try to
type check to it), parts of the generated C tables are empty (marked DEAD).

nitg-s: do not color undead types

`undead` things are dead things but that are referenced in C code, thus
need a definition to permit the link.

undead types are no more colored but the C declarations need to remain.

nitg-s: remove partial_types

rta and nitg-s now do the right thing for detecting and compiling type tests.
The partial types hack is thus useless.
