Added a Process Isolated Test Runner (#1993)

Procházet zdrojové kódy 
* Added single process isolation support to execute tests

* Address review comments

* Update README

* Removed requirement of explicit call to clear method

* Added macros for simplified usage

* Updated tests to use process isolation framework

* Adjust summary output format for isolated tests

* Updated rccl_wrap tests

* Used process isolation in AllocTests

* Used process isolation and fixed failing tests

* Modified test output, added signal handling

Updated macros to handle lambdas

* Convert argcheck tests to isolated tests

* Convert proxy tests to isolated tests

* Remove non-supported test

* Fixed file descriptor handling and clearing env vars for tests
