This begins the refactor toward letting us to use both texel buffer and
SSBO descriptors for typed buffers, which is a better workaround than
force_bindless_texel_buffers.
In this new approach, we store a mask in metadata instead of
set/binding.
When copying a descriptor, we will iterate over the masks and look up
binding directly from device->bindless_state.set_info[].
The mask is represented in terms of info index rather than set index to
avoid needless lookups. Add some new helpers to make this process
easier.

Unnecessary because the UAV counter buffer is a host memory
allocation anyway in case of host-only descriptor heaps, so
we will not read from uncached memory.

The common case is that we find an entry, so taking a writer lock should
be the rare case. We need to optimize for the case where the application

We cannot compare resource pointers or view pointers,
since the pointers might have been recycled.
This leads to a scenario where we're not updating descriptors we're
supposed to, and the GPU reads a stale descriptor.
Fixes a GPU hang in Death Stranding (and possibly lots of other weird
crashes as well).

For correctness, we will need to defer any initial resource state
handling to the queue timeline. Here, we will build an UNDEFINED ->
common layout barrier if (and only if):
- The resource is marked to care about initial layout transition.
- We are the first queue thread to observe that initial_transition
member is 1 (atomic exchange).
- The first use of the resource was not marked to be a discard.
E.g., if the first use of the resource is an alias barrier, we must
not emit an early barrier. The only we should do here is to clear the
initial_transition member, and leave it like that.
A command list maintains a list of d3d12_resources which *might* need a
transition. For the first frame a resource is used (or so), it will not
have the flag cleared yet, so multiple command lists might add the
d3d12_resource to its own transition list. This is fine, as the queue
will resolve it.
If multiple queues see the same initial transition, there might be
shenanigans, but the application must ensure there is either a
submission boundary or fence boundary between the uses. Any initial
layout transition will only be submitted after a Wait() is observed, as
submission of the transition command buffer will be in-order with other
submissions.

When building natively on Linux we simply make those visibility default.

These memory types might end up being used as fallback memory types,
which is problematic due to their tiny sizes, and unexpected performance
behavior. Generally, when we want to fallback, we should cleanly fall
back to system memory rather than a different device local type.
