st: Pass TextureTiling option from texture to memory obj

If tiling is linear, also adds the corresponding pipe bind flag
to the resource template when creating a new resource from the
memory object.

Modified TexParameteri to update the TextureTiling option only when the
texObj is not immutable (before TexStorageMem*DEXT is called to create
the texture from external memory).

v2: Ensure that memory object is not NULL before setting the
TextureTiling option (fixes TexStorage*D).

v3: Also add flag PIPE_SHARED to bindings (needed for some gallium
drivers).

v4: Use PIPE_BIND_LINEAR instead of adding a new PIPE_RESOURCE_FLAG
