Iain Sandoe c6e9823724 [C++20][Modules] Introduce an implementation module. ... We need to be able to distinguish individual TUs from the same module in cases where TU-local entities either need to be hidden (or, for some cases of ADL in template instantiation, need to be detected as exposures). This creates a module type for the implementation which implicitly imports its primary module interface per C++20: [module.unit/8] 'A module-declaration that contains neither an export-keyword nor a module-partition implicitly imports the primary module interface unit of the module as if by a module-import-declaration. Implementation modules are never serialized (-emit-module-interface for an implementation unit is diagnosed and rejected).
