PC sampling: online partial PC sampling decoding (#1004)

Browse Source 
* PC sampling: online partial PC sampling decoding

PC sampling service decodes a PC sample partially
by replacing the PC with an id of the loaded code object instance
containing PC and the offset of the PC within that code object instance.

* PC sampling: marker records removed

* PC sampling parser: minor doc update in mock

* PC sampling: introducing rocprofiler_pc_t

* NULL value of the code object id introduced.

* Clarifying documenation related to PC offset.

* PC offset documentation improvement

* PC sampling parser benchmark: Reducing the number of samples to recreate half of performance.
