Vulkan: Useful implementation of program binaries ANGLE already serializes the pipeline state for the sake of OES_get_program_binary. This serialization had limited usefulness however, since the Vulkan driver hasn't actually created any pipelines yet (which is a costly part of program creation). Simultaneously, ANGLE deferred Vulkan pipeline creation to draw time, which causes hitching. In this change, a handful of Vulkan pipelines are precreated at link time; those at least that are sure to create different blobs in the pipeline cache (different spec consts or SPIR-V generation). These pipelines are created in the program executable's cache. The cache is then merged into the shared renderer cache (for potential blob reuse by other programs). With this, two goals are achieved: - Most pipelines created at draw time hit the pipeline cache, avoiding costly compilation. - When the program binary is retrieved, the contents of the program executable's pipeline cache is also returned. On reload, the cache is recovered, resulting in faster startup.
