Previously, the 'stats' interface just used HWCPipe to interrogate performance counters from the device. HWCPipe is not widely supported, so this really only worked for Arm devices. This change allows multiple 'StatsProviders' to be used. Each provider can supply all, some, or none of the requested counters depending on its capabilities. Any counters not supplied by one provider will be requested of the next in the list until one is found, or we run out of providers. So, CPU counters can come from HWCPipe for example, whilst GPU counters come from Vulkan's extension which has been added as another provider. The StatsProvider defines an abstract interface that is implemented by the concrete providers. The parameters used for graphing the statistics have moved from the GUI classes into the StatsProvider also. This allows providers to modify the names, units and scaling of counters where these differ from the default values.
Simplifies code in device
Based on private feedback from Zandro, I've moved the construction of the stats object into the base VulkanSamples class which leaves individual samples to just request the samples they would like. The active_frame_index is no longer passed to update_stats() or the command_buffer_begun/ended() methods. It is fetched internally by the providers that require it.
size_t -> uint32_t
Override prepare_render_context() to use custom render_context. Ensures stats always sees the right render context.

Previously, the 'stats' interface just used HWCPipe to
interrogate performance counters from the device. HWCPipe
is not widely supported, so this really only worked for
Arm devices.
This change allows multiple 'StatsProviders' to be used.
Each provider can supply all, some, or none of the requested
counters depending on its capabilities. Any counters not
supplied by one provider will be requested of the next in
the list until one is found, or we run out of providers.
So, CPU counters can come from HWCPipe for example, whilst
GPU counters come from Vulkan's extension.
The StatsProvider defines an abstract interface that is
implemented by the concrete providers. The parameters used
for graphing the statistics have moved from the GUI classes
into the StatsProvider also. This allows providers to modify
the names, units and scaling of counters where these differ
from the default values.
