Simon Ser 7c99e6bd28 v3d: implement resource_get_param
Prior to this commit, the stride, offset and modifier were fetched
via WINSYS_HANDLE_TYPE_KMS. However we can't make such a query
succeed if the buffer couldn't be imported to the KMS device.

Instead, implement the resource_get_param hook to allow users to
fetch this information without WINSYS_HANDLE_TYPE_KMS.

A tiny helper function is introduced to compute the modifier of a
resource.

Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst

appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
