tweak(conhost): use circular_buffer instead of ImVector

[AvarianKnight]

Goal of this PR

Fix crash when printing a large amount of things to console (2501+) due to ItemTimes using a ImVector instead of circular_buffer.

-- this expects you to have run `con_miniconChannels "script:*"` prior
CreateThread(function()
  for i = 1, 5000 do
    print("test", i)
  end
end)

How is this PR achieving the goal

Replace ImVector with a circular_buffer so that it properly caps out at 2500 items instead of allowing it to infinity expand as a Vector, causing a crash later when it tries to remove Items and ItemKeys because they are properly restricted to 2500 items and will try to remove past the bounds if Items.

Lines 729 to 734 in 705cd79

	while ((ItemTimes.size() > 1 && (t - ItemTimes[0]) > std::chrono::seconds(10)) || Items.size() > 14)
	{
	Items.erase(Items.begin());
	ItemKeys.erase(ItemKeys.begin());
	ItemTimes.erase(ItemTimes.begin());
	}
