Subject: [PATCH] chore: add `help` Makefile target to show available targets
 (#954)

Also sets `help` as the default target, so that typing just `make` displays
the list of possible targets. Also customises the list of targets based on
TARGET_PLATFORM (because you can't build e.g. `electron-installer-dmg` when
you're on Linux).
