* add support for compiling all backends
also include the logic to select backends either based on user requests
or through some heuristics
* checkpoint for compiling all backends
* final checkpoint
all tests seem to pass when compiling all three backends simultaneasly
and forcing to use any of the three Backends.
* update PR to new envvar system
* Add host APIs for querying device ctx and remote heap pointer
* Host API to query device pointer for ROCSHMEM_DEFAULT_CONTEXT,
this is needed to support dynamic module initialization via device kernel
library bitcode.
* Host API to query remote symmetric heap pointer that can be used in
custom device kernel for RMA operations.
* Added rocshmem_ptr implementation within the Host Context class
* Enables pointer retrieval functionality for symmetric data objects
* Copy IPC pointers to host memory in RO host context

* rocshmem_config.h needs to be in a similar directory structure for
includes to work when building testers in build, and from an installed
library
* Do not change installed rocshmem.hpp
