x86/tdx: Move TDX architectural error codes into <asm/shared/tdx_errno.h>

Today there are two separate locations where TDX error codes are defined:

  arch/x86/include/asm/tdx.h
  arch/x86/kvm/vmx/tdx_errno.h

They have some overlap that is already defined similarly. Reduce the
duplication by unifying the architectural error codes at:

  asm/shared/tdx_errno.h

...and update the headers that contained the duplicated definitions to
include the new unified header.

"asm/shared" is used for sharing TDX code between the early compressed
code and the normal kernel code. While the compressed code for the guest
doesn't use these error code header definitions today, it does make the
types of calls that return the values they define. So place the defines in
"shared" location so that it can, but leave such cleanups for future
changes.

[Rick: enhance log]
[Vishal: reduce to a simple move of architectural defines only]
