Add possibility to run tests in separate process (Vulkan SC only)

During test tree iteration context uses DeviceDriverSC to collect
information about Vulkan objects used in tests ( graphics pipelines,
compute pipelines and all objects on which pipelines depend ).
After information about designated number of tests has been collected,
the subprocess is created and real tests are performed in it.
This suprocess reconstructs VkDeviceMemoryReservationCreateInfo
and pipeline cache to perform its job - required elements are created
from data gathered by main process and sent through a file.
Test results are sent back to main process for further processing
( cout and qpa logging, test status bookkeeping, etc )

Portability: handle vertex input stride

KHR_portability_subset provides minVertexInputBindingStrideAlignment
property that indicates the minimum alignment for vertex input strides.
This change fixes all cases where vertex attribute offsets exceeded
vertex buffer stride on MacOS.

Note that minVertexInputBindingStrideAlignment has value of 4 on MacOS

Fixes for robust buffer with variable pointer tests

This commit fixes several issues with robust buffer access with variable
pointers tests:

* The variable pointer tests were checking support for the
  variablePointersStorageBuffer feature but they weren't actually
  activating the feature when creating the robust buffer access device.

* Support checks were being done at instance creation time instead of
  using the proper checkSupport method.

* In-bound checks for 64-bit format accesses were only checking 4 out of
  every 8 bytes in the buffer.

* The verification routines were not taking into account 64-bit
  nonatomic accesses could be legally split into two 32-bit accesses
  that could be checked independently.

* The possibility of satisfying a (0,0,0,x) pattern in output data was
  not being checked correctly for 64-bit formats, always using 32-bit
  vectors and values.

Implement MinGW build support

This commit adds support for building with the MinGW toolchain.

This is useful as it allows Windows builds of the CTS to be
built on Linux or other platforms.
This can then either be used on Windows natively, or under the Wine
translation layer.

It can be used by either specifying a MinGW toolchain in CMake
or using the x86_64-w64-mingw32-cmake wrapper.

expression used by the GCC compiler when reading user comments
before case switch fallthrough.

The warning is triggered by -Wextra, which on GCC enables

Add missing rasterizationStream in pipeline creation

This fixes some new tests added in 0ffed122cb59b6 ("Add primitive
topologies for XFB query tests").

The rasterizationStream is not specified and it fails the expectation
of transform feedback query results.

Also if an implementation does not support
transformFeedbackRasterizationStreamSelect, streamId > 0 should not be
used as per VU :

   VUID-VkPipelineRasterizationStateStreamCreateInfoEXT-rasterizationStream-02326

Portability: fix ycbcr query tests

After adding support for VK_KHR_portability_subset
and executing CTS on MoltenVK some issues surfaced.
They are beeing resolved in a series of small CLs.

This change checks if VK_KHR_portability_subset is
available in ycbcr query tests (some of those tests
require tessellation isolines which are under feature
flag in portability).

Support alternate file path lists for loading libs

Add a new constructor to the dynamic library
loader helper class that allows callers to specify
more than one path for the desired library. The
ordered, NULL-terminated array of paths is walked
until loading one succeeds. The intention here is
to support both versioned and unversioned file
names for portability across operating systems
with different library naming conventions, e.g:

  { libfoo.so.3, libfoo.so, DE_NULL }

Should load "libfoo" on both Linux and BSD OSs.
