Adding input callback for quickernes

[SergioMartin86]

On request by Alyosha, added input poll callback for QuickerNES

For context, see: https://tasvideos.org/Forum/Posts/534219

LUA script for testing:

function poll_handler()
    print('hello')
end

event.oninputpoll(poll_handler) -- registers callback

-- This template lives at `.../Lua/.template.lua`.
while true do
	-- Code here will run once when the script is loaded, then after each emulated frame.
	emu.frameadvance();
end

Check if completed:

• I have run any relevant test suites
• I, the committer, have read the licensing terms for contributors (last updated 2024-06-22) and am compliant
