x11-drivers/nvidia-drivers: add 495.29.05

Support for Kepler cards is dropped (e.g. GTX 660, GTX 760) and,
as the ebuild should warn, Kepler users are urged to mask:

    >=x11-drivers/nvidia-drivers-471

470 is an LTS branch that should be kept updated for several years.

This version adds support for GBM, for example it now allows to
run sway and other wlroots-based wayland compositors accelerated.
That is still very experimental, expect issues.

Unkeyworded at the moment given
   A. beta with a larger-than-usual amount kernel module source
      changes that could use bit more testing
   B. egl-wayland-1.1.9 sources have not yet been released and
      1.1.8 is to remain masked
1.1.8 can still be somewhat used to test sway if wanted.
