EXT-7104 WIP Enable Build button and set necessary callbacks.

Because it is not enough to call showInstance for Build Floater it was implemented in a such way:
* set save_visibility==true in floater tools to update button toggle state properly and subscribe Build button to listen visibility changes
* added callback to observe parcel changing to set build button enabled/disabled.

KNOWN ISSUE:
if build permissions are changed button will not change state until restart/teleport
