cpu/x86/mtrr: add helper for setting multiple MTRRs

Introduce concept of var_mtrr_context object for tracking and
assigning MTRR values. The algorithm is lifted from postcar_loader
code, but it's generalized for different type of users: setting
MSRs explicitly or deferring to a particular caller's desired
actions.
