x86/tdx: Rename TDX_ATTR_* to TDX_TD_ATTR_*

The macros TDX_ATTR_* and DEF_TDX_ATTR_* are related to TD attributes,
which are TD-scope attributes. Naming them as TDX_ATTR_* can be somewhat
confusing and might mislead people into thinking they are TDX global
things.

Rename TDX_ATTR_* to TDX_TD_ATTR_* to explicitly clarify they are
TD-scope things.
