use sysctlbyname("hw.memsize") to get sytem memory size instead of host_info,
host_info is not available on tvOS, so we change to sysctlbyname which support all apple platforms
apple document didn't stat this API is available on tvOS though,

As required by the Vulkan spec.
Fixes the CTS tests
`dEQP-VK.api.info.vulkan1p2_limits_validation.khr_maintenance_3` and
`dEQP-VK.api.maintenance3_check.maintenance3_properties`.
- Don't update value of timestampPeriod on first measurement.
- Force that first measurement upon creation of MVKPhysicalDevice, so an
accurate value for timestampPeriod will be calculated when next queried.
Handle it similarly to the `A4R4B4G4` and `A4B4G4R4` formats, with a
swizzle. Vulkan requires support for this format.
Fixes the following tests:
* `dEQP-VK.api.info.format_properties.b4g4r4a4_unorm_pack16`.
* `dEQP-VK.texture.explicit_lod.2d.formats.b4g4r4a4*`
These features must be supported if the extension or `descriptorIndexing`
features is.
Conversely, disable the extension and the feature if we cannot support
the features.
Fixes `dEQP-VK.info.device_mandatory_features`.
Despite being an instance extension, `VK_EXT_debug_utils` provides some
functions that belong to the device, not the instance. Therefore, when
checking device functions, we must also check if an enabled *instance*
extension provides the function.
Also, only enable two-extension functions if *both* extensions or the
requisite core version are enabled. In all cases, these functions require
both extensions or the first extension plus some core version.
Fixes two CTS tests:
`dEQP-VK.info.instance_extension_device_functions`
`dEQP-VK.api.version_check.entry_points`
If the `fullDrawIndexUint32` feature is supported, then
`maxDrawIndexedIndexValue` must be `UINT32_MAX`. I had originally done
this when I turned the feature on, but for a while now, we've been
setting it to one less, because primitive restart can't be disabled and
the value is defined to exclude primitive restart.
The wording in the spec is ambiguous. The description of
`maxDrawIndexedIndexValue` says:
> * `maxDrawIndexedIndexValue` is the maximum index value that **can**
> be used for indexed draw calls when using 32-bit indices. *This
> excludes the primitive restart index value of 0xFFFFFFFF.* [emphasis
> added]
But the description of `fullDrawIndexUint32` says:
> * `fullDrawIndexUint32` specifies the full 32-bit range of indices is
> supported for indexed draw calls when using a VkIndexType of
> `VK_INDEX_TYPE_UINT32`. `maxDrawIndexedIndexValue` is the maximum
> index value that **may** [sic] be used *(aside from the primitive
> restart index, which is always 2<sup>32</sup>-1 when the VkIndexType
> is `VK_INDEX_TYPE_UINT32`)*. If this feature is supported,
> `maxDrawIndexedIndexValue` **must** be 2<sup>32</sup>-1; otherwise
> it **must** be no smaller than 2<sup>24</sup>-1. [emphasis added]
It's unclear whether it means that the primitive restart index is to be
ignored, or the maximum draw index must account for it.
The alternative is to disable `fullDrawIndexUint32` because we cannot
set `maxDrawIndexedIndexValue` to `UINT32_MAX`; but that might mislead
programs into thinking that we only support 24-bit vertex indices.
Fixes the rest of the `dEQP-VK.info.device_properties` test.
Previously, we were erroneously failing create calls that specified zero
external handle types (as opposed to omitting external memory info
entirely).
Fixes 6 tests under
`dEQP-VK.api.buffer_memory_requirements.create_no_flags.ext_mem_flags_included.*`
- Move patch point tracking from pipeline state to render state, and

- Move sample location tracking from renderpass input to pipeline
static or dynamic state tracking.
