Remove unconditional prints to stdout

[gshtras]

In certain places across the codebase there are unconditional std::cout, such as
https://github.com/ROCm/aiter/blob/main/csrc/include/aiter_hip_common.h#L84 and others
These printouts ignore the general AITER_LOG_LEVEL and cannot be suppressed.
Please make them respect the logging verbosity setting
