Check that the driver supports both BUFFER_OFFSET and BYTES_WRITTEN
encode feedback flags before creating the query pool, failing with
EINVAL if either is missing.
Set these flags explicitly instead of masking off HAS_OVERRIDES with a
bitwise NOT, which could pass unrecognized bits from newer drivers to
vkCreateQueryPool causing validation errors and
crashes.
