[MERGE #1306 @obastemur] cross-platform: fix stack related issues on macOS

Merge pull request #1306 from obastemur:fixed_stack_osx

We have all tests are passing for macOS now.

notes on updates:

 ~~Main thread default stack limit is 8MB while `pthread_get_stacksize_np` may return lower value.~~

~~OSX implementation of Pthread stack size is 512KB~~
 - Sets 64MB process stack limit through macOS linker to match our testing needs

edit: removed additional pthread updates. It was kind of a nice to have but at the moment not needed. Going to visit that separately.
