* Unifying these views means that constant buffers have all the same
reformatting and it avoids having multiple paths for what is now effectively
the same control (a buffer can either have fixed data, repeating data, or
both)
* GL and Vulkan allow buffers to have fixed variables before a trailing AoS
unbounded array. These fixed variables can't be easily displayed in a table
and previously we skipped them. Now we display these in a tree format.
* We also support formats which don't have an unbounded array at all and display
these just with the tree. This will allow the BufferViewer to subsume the
capabilities of the ConstantBufferPreviewer (though it needs to handle opaque
non-buffer-backed variables, and slot-following).
* This allows the calling code to pass a hint of what packing is known or likely
to be used, meaning less generated manual offsetting/padding when the implicit
rules cover it.
* Instead of having a global tight/non-tight we now let the format string
specify the packing rules (defaulting to scalar - i.e. tight packing as
before), and use the resulting properties to calculate packing.
* Most of the main entry points that can fail with relevant reasons now has a
way of specifying a message to return with it. This message can be displayed
to the user to give more information or context about an error.
* The 'no to all' option should always be present if there are multiple unsaved
captures across the connections, even if the current connection only has one
capture and so otherwise wouldn't have a 'no to all' option.
* The 'no to all' option will always discard all unsaved captures in all
connections when closing the window, if the user clicks no on the confirmation
of this, abort the close operation entirely and let them decide how to handle
it (e.g. discarding/saving captures in connections individually).
* For some reason using != on these QSet<QString> fails in release only on
github's CI only. I don't know what is broken on their runners but this
workaround fixes it.
