GZDoom aborts with 'Failed to submit command buffer' error on saving a game when open source Intel Vulkan driver (part of Mesa 3D package) is used on Linux
This driver generates VK_DEVICE_LOST error when vkWaitForFences() is called with zero fence count. It must be greater than zero according to Vulkan spec
Provided uniform way to handle lifetime of some of Vulkan resources
This helps to avoid issues like descriptor set that outlives its pool

Ò was inverted and therefore had inconsistent shading, which is fixed; Ů had darkened corners to give in to the umlaut, but was found to not be necessary; Љ and Л are both smoothened according to how the letter looks in the console font, and Џ is slightly shortened (to match up with the letter Q in terms of size).
Previously, the characters И, Й, Ѝ and Я had the appearance of inverted versions of their Latin counterparts, N and R. With inverted shading, the letters turned out difficult to read; therefore, this commit reverts them to their old appearance (from the Russian Doom port, made by @JNechaevsky).
