Commented Read and Write in test app

Don't need it now and it is broken anyway
SetOutputReport cannot be used

There should exist OUTPUT items in HID COLLECTION, but currently Pen
collection does not have any. Will try another approach (WriteFile).
Commenting default stuff
Missed a few default tests
add a define for output report
add test code - WriteFile to hid device
HID_REPORT_DESCRIPTOR changes

remove default stuff (collection from sample). Add a copy of Pen
collection but with all INPUTs changed to OUTPUTs, and all Usages
changed to Vendor usage.
