From working with serialized CPU profile data we noticed the following: 1. It is easier to read shorter hex strings when looking up CPUID leaves in the serialized CPU profile data. 2. It is preferable to also have sub-leaf ranges hex encoded. 3. We still want to keep serializing the adjustments to 10 character hex strings. Some of the convenience functions introduced here will also be utilized in the upcoming MSR adjustments PR in order to serialize register addresses.

This PR makes some changes to the way we serialize CPUID leaf and sub-leaves in the CPU profiles. When debugging CPU profiles I noticed that it is easier to deal with shorter hex strings for the leaves and that it would also be nice to have the sub-leaf ranges specified in terms of hex as well.
We do however want to keep serializing the adjustments as 10 byte hex strings which we do not change here (only the code).
We don't bother regenerating profiles in this PR, because there is no functional change, and we have to regenerate them in #70 anyway.
