cmake - Static bundles for the IAR toolchain[DRAFT]

We made a release to Asensing but the IAR library was not bundled
properly and static linking was not done.
The plan is to use `add_static_library_bundle` but, the archive code is
not compatible with IAR.

A flag was added that is only set during IAR compilation and installs.

Currently, we are using CMAKE but plan to move to Bazel after this patch
release
