The goal is to progressively propagate all the derived type info that is currently in the runtime type info globals into a FIR operation that can be easily queried and used by FIR/HLFIR passes. When this will be complete, the last step will be to stop generating the runtime info global in lowering, but to do that later in or just before codegen to keep the FIR files readable (on the added type-info.f90 tests, the lowered runtime info globals takes a whooping 2.6 millions characters on 1600 lines of the FIR textual output. The fir.type_info that contains all the info required to generate those globals for such "trivial" types takes 1721 characters on 9 lines). So far this patch simply starts by replacing the fir.dispatch_table operation by the fir.type_info operation and to add the noinit/ nofinal/nodestroy flags to it. These flags will soon be used in HLFIR to better rewrite hlfir.assign with derived types.
