Subject: perf kvm: Add dimensions for KVM event statistics

To support KVM event statistics, this patch firstly registers histograms
columns and sorting fields; every column or field has its own format
structure, the format structure is dereferenced to access the dimension,
finally the dimension provides the comparison callback for sorting
result.
