Bug 1305777 - Clean up touch simulator after old RDM removal. r=ochameau

Only `simulator-core` is used by new RDM via the Emulation actor, so I've moved
this server side and renamed it to `touch-simulator`.

rename : devtools/shared/touch/moz.build => devtools/server/actors/emulation/moz.build
rename : devtools/shared/touch/simulator-core.js => devtools/server/actors/emulation/touch-simulator.js
