build(app): Collect artefacts in a single location
This patch consolidates all the apps outputs files into a
single output folder corresponding to the build configuration.
This allows CI scripts to package binaries from a single location.
The `fake_host` build now generates elf, map and dump files
similar to RMM core in the output folder.
The app bin file names are changed for uniformity.
