e913b4870a vkformat: try UNORM format first and decouple them from colorimetry
From the spec (chapter 34, v1.3.283):

````
UNORM: the components are unsigned normalized values in the range [0, 1]

SRGB: the R, G and B components are unsigned normalized value that represent
      values using sRGB nonlinear encoding, while the A component (if one
      exists) is a regular unsigned normalized value
```

The difference is the storage encoding, the first one is aimed for image
transfers, while the second is for shaders, mostly in the swapchain stage in the
pipeline, and it's done automatically if needed [1].

As far as I have checked, other frameworks (FFmpeg, GTK+), when import or export
images from/to Vulkan, use exclusively UNORM formats, while SRGB formats are
ignored.

My conclusion is that Vulkan formats are related on how bits are stored in
memory rather their transfer functions (colorimetry).

This patch does two interrelated changes:

1. It swaps certain color format maps to try first, in both
gst_vulkan_format_from_video_info() and gst_vulkan_format_from_video_info_2(),
the UNORM formats, when comparing its usage, and later check for SRGB.

2. It removes the code that check for colorimetry in
gst_vulkan_format_from_video_info_2(), since it not storage related.

c760c72f7a vkformat: fetch correctly feature flags2
Feature flags2 are fetch through VkFormatProperties3KHR and needs more guards
checking.

Moved out all the feature flags fetching to another function for clarity.

c24b47ecee vkformat: use VK_KHR_get_physical_device_properties2 to guard
and VK_KHR_format_feature_flags2 rather than a meaningless version handling.

Also the patch brings back the usage of features2 for video extensions, use KHR
version to support the guarded symbols.

634fc913a6 vulkan/format: don't assign an uneeded boolean
We don't actually need the basics_primary/secondary boolean.  The

necessary.

d20d94cc48 vkformat: also use the correct srgb vs unorm when using older
gst_video_info_from_video_info()

display.

4d3b03e8e8 vkformat: invert srgb and multiplane && planes > 1 checks
The primary format for RGB includes sRGB transfer but was not actually
being used.

The !(no_multiplane && planes > 1) check for YUV resulted in those
formats never being used.

6920166af4 vulkan: fix C2099 error with VS2019
As VK_FORMAT_FEATURE_2_xxx are defined as static const variable, the
vscoce C compiler prevents the initialization of the  vk_usage_map
structure with error "C2099: initializer is not a constant".

Init the structure separately.

06d793033d vulkan/format: use basic features (v1) as fallback
if vkGetPhysicalDeviceFormatProperties2 isn't available.

This approach assumes that, for basic features flags symbols,
VkFormatFeatureFlagBits and VkFormatFeatureFlagBits2 are binary equivalent.

35dbd9f92c vkformat: add gst_vulkan_format_from_video_info_2()
The purpose of this function is to get more info about the mapped Vulkan format
from the GStreamer format, since they can be multiple Vulkan formats for one
GStreamer format.

Also a Vulkan format may have certain usage and aspects that must be verified.
