gui-qt: add copy test environment summary to compatibility menu (#3962)

when a game already has a compatibility report, the context menu only
lets you copy the vita3k build summary. this adds a second action to
also copy the test environment summary (os, cpu, gpu, ram) so users
can paste it into existing issue comments without having to manually
type it out.

closes #3586
