PC sampling: integration test with instruction decoding (#929)

* PC sampling: integration test with instruction decoding

* PC sampling: verifying internal and external CIDs

The PC sampling integration test has been extended
to verify internal and external correlation IDs.

* tmp solution of using Instructions as keys

* wrapper for HIP call

* PCS integration test: ld_addr as instruction id

For the sake of the integration test, use  as the
instruction identifier. To support code object unloading
and relocations, use  as the identifier
(the change in the decoder is required).

* PCS integration test: removing shared_ptr

Completely removing usage of shared pointers.

* PCS integration test: removing decoder

When a code object has been unloaded, ensure all PC samples
corresponding to that object are decoded, prior to removing
the decoder.

* PCS integration test: fixing build flags and imports

* PCS integration test: fixing labels

* PCS integration test: cmake flags fix

* PC sampling cmake labels renamed

* PCS integration test refactoring

* PCS integration test: minimize usage of raw pointers

* PCS integration test: at least one sample should be delivered.

* PC sampling lables: pc-sampling
