include/cpu/x86: introduce new helper for (un)setting MSRs

msr_set_bit can only set single bits in MSRs and causes mixing of bit
positions and bitmasks in the MSR header files. Thus, replace the helper
by versions which can unset and set whole MSR bitmasks, just like the
"and-or"-helper, but in the way commit 64a6b6c was done (inversion done
in the helper). This helps keeping the MSR macros unified in bitmask
style.

In sum, the three helpers msr_set, msr_unset and msr_unset_and_set get
added.

The few uses of msr_set_bit have been replaced by the new version, while
the used macros have been converted accordingly.
