d: Fix ICE in TypeInfoDeclaration, at dmd/declaration.c (PR100967)

Generate a stub TypeInfo class even if the root Object class is missing.
The front-end will take care of issuing an error and abort the
compilation when running semantic on constructed TypeInfo objects.

The errors issued by the code generation pass relating to missing or
disabled RTTI has been consolidated into a single function, so that a
meaningful error will be emitted before the front-end terminates.

gcc/d/ChangeLog:

PR d/100967
* d-frontend.cc (getTypeInfoType): Move TypeInfo checks to
check_typeinfo_type and call new function.
* d-tree.h (check_typeinfo_type): Declare.
* typeinfo.cc: Include dmd/scope.h.
(create_frontend_tinfo_types): Generate front-end types even if
Object
is missing.
(build_typeinfo): Move TypeInfo checks to check_typeinfo_type and
call
new function.
(check_typeinfo_type): New function.
