SampleApp: Build list of devices dynamically

SampleApp: Build list of devices dynamically

Build list of devices available to SampleApp user dynamically.

This works around the problem that in the future, there might be more
device configurations than device type enumerations. Concretely, the
configurable properties could be msaa sample count, nvpr or not, as well
as API type.

SkOSMenu used varargs, which selects the number of entries
during compile time very rigidly. Change it to use SkTArray.

Changes '--gpu' to  '--startWith gpu'
