  [flang] Lower PRIVATE component names safely (#66076)

It is possible for a derived type extending a type with private
components to define components with the same name as the private
components.

This was not properly handled by lowering where several fir.record type
component names could end-up being the same, leading to bad generated
code (only the first component was accessed via fir.field_index, leading
to bad generated code).

This patch handles the situation by adding the derived type mangled name
to private component.
