Closes #1556

This PR adds types that enables to store time in different representations like simple milliseconds, number of frames, etc. And also allow to interconvert between them. It also provides functions for formatting time in different kinds of formats. Certain functions are integrated into C codebase.

In comparision with PR #1556, I initiated lib_ccxr/utils/time.rs for only functions mentioned in utility.c & lib_ccxr/time/units.rs for necessary implementation(struct, enums, functions) of any work related to timings.
This lib_ccxr/time will be continued later as well for more timings code coversion
