* [Vulkan] Enable instance/device extensions
- Vulkan requires that extensions be explicitly enabled if used.
Explicitly list out which extensions are required (currently none)
and which are optional.
* [Vulkan] Extract device information from vulkan API.
- Based on vkGetPhysicalDeviceProperties and
vkGetPhysicalDeviceFeatures, determine which Vulkan capabilities are
supported, pack into a Target.
* [Vulkan] Query instance-supported apiVersion before creating instance
- Previously, vkCreateInstance was called to initialize Vulkan 1.0.
* [Vulkan] Moved options for dedicated allocation and push descriptors to environment variables
- Query support for dedicated allocation and push descriptors along
with the rest of the device support. Move the options to disable
their use from compile-time variables to environment variables
`TVM_VULKAN_DISABLE_PUSH_DESCRIPTOR` and
`TVM_VULKAN_DISABLE_DEDICATED_ALLOCATION`.
* [Vulkan] Move option for vulkan validation layers to environment variable
- Moved to enable faster use as a debug tool. If
`TVM_VULKAN_ENABLE_VALIDATION_LAYERS` is a non-empty string,
validation layers will be enabled.
* [Vulkan] Explicitly enable vulkan features in device creation
- Vulkan requires that features be explicitly enabled before use. For
each feature that the device supports and a shader might use,
declare it in the call to `vkCreateDevice`.
* [Vulkan] Avoid repeated queries for device attributes.
- Implement `VulkanDeviceAPI::GetAttr` based on the per-device values
stored in the Target. This pulls all logic for querying device
parameters is in a single location.
* [Vulkan] Implement "from_device" flag for the vulkan target.
- With the number of device capabilities that may or may not be
supported by a vulkan driver, it can be tedious to input them.
Specifying "-from_device=0" now indicate that any unspecified values
should be read from the device.
* [Vulkan][Codegen] Read vulkan device capabilities/limits from Target
- Previously, the codegen assumed that all device features were
present. Now, the codegen reads device capabilities from the
Target, and throws an error if codegen would require use of an
unsupported feature.
