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.
