Vulkan SDK 1.1.77 released

[JeGX]

Overview of changes and additions to Vulkan SDK 1.1.77

- Linux SDK is now packaged as a tar.gz file instead of a .run file. Previously the run file created a VulkanSDK directory and then expanded the SDK into the VulkanSDK/1.1.xx.y directory. The tar file now simply expands the SDK into a directory of the form 1.1.xx.y.

- Many bug fixes, increased validation coverage and accuracy improvements, and feature additions

- New extensions for this SDK release:
    VK_KHR_get_display_properties2
    VK_KHR_draw_indirect_count
