Add support for 64 bit integer atomic operations in shaders.

Browse Source 
Add the following flags to `wgpu_types::Features`:

- `SHADER_INT64_ATOMIC_ALL_OPS` enables all atomic operations on `atomic<i64>` and
  `atomic<u64>` values.

- `SHADER_INT64_ATOMIC_MIN_MAX` is a subset of the above, enabling only
  `AtomicFunction::Min` and `AtomicFunction::Max` operations on `atomic<i64>` and
  `atomic<u64>` values in the `Storage` address space. These are the only 64-bit
  atomic operations available on Metal as of 3.1.

Add corresponding flags to `naga::valid::Capabilities`. These are supported by the
WGSL front end, and all Naga backends.

Platform support:

- On Direct3d 12, in `D3D12_FEATURE_DATA_D3D12_OPTIONS9`, if
  `AtomicInt64OnTypedResourceSupported` and `AtomicInt64OnGroupSharedSupported` are
  both available, then both wgpu features described above are available.

- On Metal, `SHADER_INT64_ATOMIC_MIN_MAX` is available on Apple9 hardware, and on
  hardware that advertises both Apple8 and Mac2 support. This also requires Metal
  Shading Language 2.4 or later. Metal does not yet support the more general
  `SHADER_INT64_ATOMIC_ALL_OPS`.

- On Vulkan, if the `VK_KHR_shader_atomic_int64` extension is available with both the
  `shader_buffer_int64_atomics` and `shader_shared_int64_atomics` features, then both
  wgpu features described above are available.
