Any thread we create may end up creating/submitting at least a noop job, which is a shared object. Before multisync, this was an issue only for the creation of the job itself, but with multisync we can also modify parameters of the noop job every time it is used (for signaling and serialization configuration). This change adds a noop mutex that all threads (main, wait and master) take before submitting a noop job to ensure concurrent access is not an issue. Fixes flakyness observed with multisync with the following test: dEQP-VK.api.command_buffers.secondary_execute_twice Reviewed-by: Melissa Wen <mwen@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15342>
