Describe interfaces with PROGMEM descriptor rows; drop the switch tables

Browse source 
AlexaInterfaces.h/.cpp hold one row per interface in program memory (28: namespace,
version, property names, flags, type), each row and string an object of its own, so
the linker keeps only the rows a sketch names. addCapability(AlexaInterfaceType) is
an always-inline switch that folds to one row; a type without a row is refused with
an error. The Event handler gets its type from the capabilities of the device.
Versions follow the interface pages (EndpointHealth 3.1, ThermostatController 3.2),
HumiditySensor is new, the two withdrawn interfaces and AlexaInterfaceUtils are gone.
Display category names are in flash. The discovery objects of the five examples are
unchanged: 14 new host tests compare them with what the previous commit announced.
basicLight on a D1 mini: static RAM 34,508 -> 30,788, flash 338,533 -> 330,509;
it links two rows, EndpointHealth and PowerController. Host tests: 47 -> 61.
