net/gve/base: fix build with Fedora Rawhide

[ upstream commit f0d9e78 ]

Currently, a number of integer types are typedef'd to their corresponding
userspace or RTE values. This can be problematic if these types are
already defined somewhere else, as it would cause type collisions.
This patch changes the typedefs to #define macros which are only defined
if the types are not defined already.

Note: this was reported by OBS CI on 2024/10/17, when compiling DPDK
in Fedora Rawhide.

Fixes: c9ba2ca ("net/gve/base: add OS-specific implementation")
Fixes: abf1242 ("net/gve: add struct members and typedefs for DQO")
