VSync on Linux

[GabeRundlett]

VSync (present mode FIFO) and even MAILBOX seem to not work on Linux. Using FIFO results in a fine app, until one tries to resize the window and it eventually hangs and reports a device lost. If anyone has Linux experience, let us know what should be done. https://github.com/Ipotrick/Daxa/blob/55182fae5687005da642452724db921a922a4fec/src/impl_swapchain.cpp#L276C43-L276C43
