android: add support for classic dri-drivers (v2)

(v1) Changelog:

-Ddri-drivers option is added in MESON_GEN_NINJA
$(foreach ) cycle copies *_dri.so files to /vendor/lib{64}/dri/

(v2) Changelog

Remove unwanted Symlinks created for classic dri drivers
Update the comments describing each step
Rename .symlinks.timestamp to .targets.timestamp
Squash all the changes in one commit to facilitate picking in mesa stable

HowTo:
BoardConfig.mk: BOARD_MESA3D_CLASSIC_DRIVERS defines the list of classic dri drivers
example: BOARD_MESA3D_CLASSIC_DRIVERS := i965

Fixes: 8621bd8d ("android: Add scripts to build using meson")
