Before we were falling back to always emitting a pipeline barrier, which effectively kills any point of having the event. But with sync2 and the guarantee that src/dst dependency infos match, we can instead emit the flushes before writing the event and actually use the event as intended. As a bonus, this also allows the BV to run ahead of the BR. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/40552>

/** Expands pipeline stage group flags
|
|
*
|
|
* Some stages like VK_PIPELINE_SHADER_STAGE_2_ALL_GRAPHICS_BIT represent more
|
|
* than one stage. This helper expands any such bits out to the full set of
|
|
* individual stages bits they represent.
|
|
*
|
|
* Note: This helper does not handle BOTTOM/TOP_OF_PIPE. You probably want to
|
|
* use vk_expand_src/dst_stage_flags2() instead.
