edid-decode: build: add support for building with meson
This also removes the old Makefile based build-system.
The immediate reason for adding support for meson is that this allows us
to include edid-decode as a subproject in libdisplay-info.
v3:
* Declare a meson variable for the executable to make it possible to
get it via subproject.get_variable()
v2:
* Remove the make build-system
* Adjust the README on how to build/install with meson
* Fix installing for the wasm-build
