dev-libs/xdna-driver: add 2.21.75-r2 (depmod.d override)

Borrowed from ::guru's xdna-driver-2.21.75-r2: replace the /usr/lib/modules-
load.d/amdxdna.conf + /etc/modprobe.d/amdxdna.conf 'install amdxdna /sbin/insmod ...'
pair with a single /etc/depmod.d/amdxdna.conf carrying 'override amdxdna * extra'.
depmod's override directive is the canonical mechanism for 'prefer out-of-tree over
in-tree' (xdna-driver lands in kernel/drivers/accel/amdxdna/ from 6.10). Plain
modprobe amdxdna now resolves to extra/amdxdna.ko with normal lsmod / modprobe -r
semantics, instead of the insmod-by-full-path workaround that broke dep tracking and
rmmod. Dropping the modules-load.d entry is also correct: the module has
MODULE_DEVICE_TABLE(pci, ...) so udev autoloads on device presence; forcing load at
boot only spewed errors on hosts without an XDNA NPU. Live ebuild gets the same
swap. -r1 retained for rollback.

dev-libs/xdna-driver: import 2.21.75-r1 + 999999 from ::guru

Kernel-side AMD XDNA / amdxdna driver from amd/xdna-driver. Imported
unchanged from ::guru (carries llvm-support and try-compile-config
patches plus the amdxdna.conf modprobe shim).

Final piece of the XRT/XDNA stack cascade for sci-ml/fastflowlm;
retire when fastflowlm lands in ::guru.
