fix(apache): isolate raw adapters from host modules

[regyssilveira]

Summary

• keep Horse.Provider.RawAdapters out of Apache, ISAPI, CGI, and FastCGI dependency graphs
• retain raw request/response handling for epoll, IOCP, and HttpSys providers
• fail compilation if a host-managed application accidentally links RawAdapters again

This restores the initialization order expected by Web.HTTPD24Impl, preventing the exported Apache module record from being observed zero-filled.

Fixes #558.

Validation

• Apache Win64 full build: Delphi 10 Seattle, Delphi 11, and Delphi 13
• confirmed no Horse.Provider.Raw*.dcu is emitted in the Apache build graph
• confirmed the Apache DLL exports apache_horse_module
• ISAPI Win32 and CGI Win32 full builds on Delphi 13, also with zero raw-adapter DCUs
• IOCP Win64 and HttpSys Win64 full builds on Delphi 13, both retaining raw-adapter DCUs
• epoll Linux64 full build on Delphi 13
• epoll Linux64 full build with FPC 3.2.2 in Docker
• direct HORSE_APACHE compilation of Horse.Provider.RawAdapters fails with the intended guard

An Apache runtime was not available locally, so runtime loading with httpd.exe -t was not performed.
