bufferDeviceAddress: opaqueCaptureAddress support

This CL ads an implementation of these functions:
- vkGetBufferDeviceAddress. Relevant spec text:
 "The 64-bit return value is an address of the start of pInfo->buffer.
  ...
  If the buffer was created with a non-zero value of
  VkBufferOpaqueCaptureAddressCreateInfo::opaqueCaptureAddress or
  VkBufferDeviceAddressCreateInfoEXT::deviceAddress, the return value
  will be the same address that was returned at capture time."

  Note: SwiftShader does not expose VK_EXT_buffer_device_address, so
        an assert was added, along with a comment explaining what to
        do it we ever support this extension.

- vkGetBufferOpaqueCaptureAddress. Relevant spec text:
  "The 64-bit return value is an opaque capture address of the start
   of pInfo->buffer.
   If the buffer was created with a non-zero value of
   VkBufferOpaqueCaptureAddressCreateInfo::opaqueCaptureAddress the
   return value must be the same address."

- vkGetDeviceMemoryOpaqueCaptureAddress. Relevant spec text:
  "The 64-bit return value is an opaque address representing the
   start of pInfo->memory.
   If the memory object was allocated with a non-zero value of
   VkMemoryOpaqueCaptureAddressAllocateInfo::opaqueCaptureAddress,
   the return value must be the same address."

This implicitly means adding support for OpaqueCaptureAddress in
DeviceMemory and Buffer objects. This is required by the
bufferDeviceAddress feature, which is mandatory in Vulkan 1.3.

This CL does not add support for SPV_KHR_physical_storage_buffer,
which is the other half of the bufferDeviceAddress feature, so the
bufferDeviceAddress feature isn't be exposed in this CL.
