bug-fix: snprintf prints NULL in place of the last character (#10419)

* bug-fix: snprintf prints NULL in place of the last character

We need to give snprintf enough space to print the last character and the null character, thus we allocate one extra byte and then ignore it when converting to std::string.

* add comment about extra null-term byte requirement

vulkan: request round-to-even for fp16 in im2col/rope_head (#10767)

Vulkan doesn't mandate a specific rounding mode, but the shader_float_controls
feature allows rounding mode to be requested if the implementation supports it.

vulkan: disable spirv-opt for coopmat shaders (#10763)

There are some bugs in the 1.3.296 SDK, so disable this. It isn't strictly
necessary anyway.

Add missing dependency on vulkan-shaders-gen, so shaders get recompiled when it
changes.

Fix coopmat support reporting when glslc doesn't support NV_coopmat2.
