linuxkpi: Add support for statically-allocated kfifo
The main difference with the dynamically allocated version is that the
structure is initialized with `DECLARE_KFIFO()` which takes the number
of items as an additional argument compared to `DECLARE_KFIFO_PTR()`.
The declared structure is then initialized with `INIT_KFIFO()` which
sets all fields to 0, except `total` which is computed from the size of
the array passed to `DECLARE_KFIFO()`.
The amdgpu DRM driver started to used this in Linux 6.10.
