libsysprof-analyze: add SysprofDocumentCtrset

Browse Source 
This represents the SysprofCaptureCtrset and allows fetching the raw values
for a given counter. These are raw because they may not be endian swapped
and that is the responsibility of the consumer.

SysprofDocument will use these eventually to store the values for a given
counter and the time of the value shift.
