x86/fpu/mpx: Rework MPX 'xstate' types
MPX includes two separate "extended state components". There is no real need to have an 'mpx_struct' because we never really manage the states together. We also separate out the actual data in 'mpx_bndcsr_state' from the padding. We will shortly be checking the state sizes against our structures and need them to match. For consistency, we also ensure to prefix these types with 'mpx_'. Lastly, we add some comments to mirror some of the descriptions in the Intel documents (SDM) of the various state components.
