Simple Vulkan Synchronization Versions Save

Alpha.8 adds a host preinitialization state for linear images, as well as a number of new access sets for extensions released since the last update.

Alpha.7 incorporates a number of fixes from @gwihlidal, and fixes handling of pipeline stages in the presence of multiple access types or barriers in light of other recent changes.

Alpha.6 fixes a typo (VK_ACCESS_TYPE_MEMORY_READ|WRITE_BIT should have been VK_ACCESS_MEMORY_READ|WRITE_BIT), and sets the pipeline stage src and dst flag bits to VK_PIPELINE_STAGE_TOP_OF_PIPE_BIT and VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT during initialization, not 0 as per alpha.5

Initial version of thsvs_simpler_vulkan_synchronization.h

Alpha.5 now correctly zeroes out the pipeline stage flags before trying to incrementally set bits on them... common theme here, whoops. (#5)

Alpha.4 now correctly zeroes out the access types before trying to incrementally set bits on them (!)

Alpha.3 changes the following:

Uniform and vertex buffer access in one enum, matching D3D12_RESOURCE_STATE_VERTEX_AND_CONSTANT_BUFFER:

• THSVS_ACCESS_ANY_SHADER_READ_UNIFORM_BUFFER_OR_VERTEX_BUFFER

Color read and write access, matching D3D12_RESOURCE_STATE_RENDER_TARGET:

• THSVS_ACCESS_COLOR_ATTACHMENT_READ_WRITE

Also the "THSVS_ACCESS_SHADER_READ_SAMPLED_IMAGE" enums have been renamed to the form "THSVS_ACCESS_SHADER_READ_SAMPLED_IMAGE_OR_UNIFORM_TEXEL_BUFFER"

Alpha.2 adds four new resource states for "ANY SHADER ACCESS":

• THSVS_ACCESS_ANY_SHADER_READ_UNIFORM_BUFFER
• THSVS_ACCESS_ANY_SHADER_READ_SAMPLED_IMAGE
• THSVS_ACCESS_ANY_SHADER_READ_OTHER
• THSVS_ACCESS_ANY_SHADER_WRITE

Alpha.1 adds three new resource states:

• THSVS_ACCESS_GENERAL (Any access on the device)
• THSVS_ACCESS_DEPTH_ATTACHMENT_WRITE_STENCIL_READ_ONLY (Write access to only the depth aspect of a depth/stencil attachment)
• THSVS_ACCESS_STENCIL_ATTACHMENT_WRITE_DEPTH_READ_ONLY (Write access to only the stencil aspect of a depth/stencil attachment)

It also fixes a couple of typos, and adds clarification as to when extensions need to be enabled to use a feature.
