cmake: changes required for qurt build

Fixed CMakeLists.txt to be consistent with module.mk
Converted PX4_TICKS_PER_SEC to define for QURT to get around relocation error
Added stubs for QURT so building a full executable can be tested. This will
enable CI testing without the full Hexagon SDK.

Created a dummy build_git_version.h so I did not have to figure out
how to generate it.

Commented out topic_listener.cpp from src/systemcmds/CMakeLists.txt
because it depends on a generated cpp file.

Link doesn't work mut many modules build

Managed to get the deps set up to build the qurt modules using a

NuttX link options are being set somewhere that break the qurt build

The current approach of distributing submodule inclusion logic makes
evert parent dir need to know about all build targets.

This approach goes back to the previous way of centralizing the build
dirs in a single file.
