Meson build system support

[nazar-pc]

veque looks useful, especially in comparison with std::deque.

I'd like to use it in mediasoup, but for that Meson build system support would be needed.

Creating this for tracking purposes, will likely contribute later (should be very simple) unless you're opposed to including it.
