GTEST: reduce stack usage in tests
What?
This PR reduces stack memory usage by converting stack allocations to heap in various UCX tests.
Why?
Customers with limited stack sizes have recently experienced stack overflow issues when running UCX. The goal is to ensure that the entire UCX runs within a defined stack size threshold. By reducing the stack frame size in tests, this change helps in testing the runtime stack usage, ensuring that it starts within the threshold.
How?
This PR reduces stack usage by creating separate helper functions for excessive inline functions calls.
