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.
