* Actually creating a 64-bit spinbox is not feasible without constructing it
almost from scratch due to how much QAbstractSpinBox depends on private
internals that can't be overridden. Instead use a QDoubleSpinBox with no
decimals since we don't need the full 64-bit range, and the mantissa of a
double is enough.
* E.g. on D3D12 we can debug DXBC shaders but not DXIL shaders. On vulkan this
will allow us to have the UI work better when encountering shaders with
unsupported capabilities or extensions.
* There was a race condition where the newly created HWND surface could
be resized during swap chain creation. This causes a
`VK_ERROR_DEVICE_LOST`, but is very timing dependent.
* The fix was to finish the resize, via `ResourcePreview::setActive()` /
`QWidget::show()` before scheduling any async functions that could
create a swapchain, namely `IReplayOutput::AddThumbnail()`.
* We change to use VarType instead of CompType for signature parameters which
allows us to represent different types of variables beyond just
unsigned/signed integer and float.
* For D3D this should be equivalent since name == bindpoint, but for SPIR-V this
prevents the same binding being loaded into multiple SSA variables from being
added every time.
* For vulkan debugging where high-level variables are not scattered amongst
vectors, there's no point in having the whole tree expanded for source mapping
struct-to-struct or array-to-array.
Previously this data was a reference to the current pipeline state, so
when the selected event changed, the ShaderViewer's bindpoint mappings
would be inaccurate.
When a resource is accessed, it is now tracked by the debug step. The
shader viewer has a new panel to display resources accessed up to the
current step, with context menus to go to previous/next access of a
specific resource.
