Subject: [PATCH v6 05/10] x86/virt/tdx: Add missing header file inclusion to local tdx.h

Compiler attributes __packed and __aligned, and DECLARE_FLEX_ARRAY() are
currently used in arch/x86/virt/vmx/tdx/tdx.h, but the relevant headers
are not included explicitly.

There's no build issue in the current code since this "tdx.h" is only
included by arch/x86/virt/vmx/tdx/tdx.c and it includes bunch of other
<linux/xxx.h> before including "tdx.h".  But for the better explicitly
include the relevant headers to "tdx.h".  Also include <linux/types.h>
for basic variable types like u16.
