Compile Gallium VA driver on Mesa (v2)

[hmtheboy154]

Original patch for Android.mk on Mesa3d is made by aleasto, port to aospext by me with some help by rsglobal

To compile Gallium VA, put this in BoardConfig.mk : BOARD_MESA3D_GALLIUM_VA := enabled
BOARD_MESA3D_GALLIUM_VA_CODECS := h264dec h264enc h265dec h265enc vc1dec

(v2):

• Fix an issue in which the build only create link on lib instead of lib & lib64
• Compatiable with latest Mesa 24.3 as Gallium VA is now being integrated directly into libgallium_dri.so

Compatiable with latest Mesa 24.3 as Gallium VA is now being integrated directly into libgallium_dri.so

Do we really need that old Mesa support that requires all that complex logic of populating symlinks?
I planned to drop gallium DRI symlinks after some time (maybe a year). To keep things clean.

How about keeping support gallium VA for the latest mesa only?

imo I think that we can keep old Mesa support for a while, maybe till the end of this year. Currently older Android version of BlissOS still using 24.0. I'd also like to know @maurossi thoughts about this.
