The Raspberry Pi 5 only supports Vulkan v1.2, and doesn't have support for Int8, Int16, or Int64 types.

The main changes introduced in this PR are:

  1. Handle arbitrary split sizes for device allocation requests
    • The RPI driver appears to require an allocation larger than the requested size which is padded to next alignment boundary
  2. Refactor descriptor set updates to "push" directly, instead of allocate, update and bind (if supported).
  3. Refactor tests to check for type support

Fixes #8494.
