Reclassification of Mesa as Required in the libvdpau-va-gl documentation - r12.0-974

[rhubarbpieguy]

Mesa is classified as a "Runtime Dependency" in the libvdpau-va-gl documentation but is required to compile libvdpau-va-gl and should be listed as Required. Compiling libvdpau-va-gl without Mesa produces the following:

-- Checking for module 'gl'
-- Package 'gl', required by 'virtual:world', not found
CMake Error at /usr/share/cmake-3.27/Modules/FindPkgConfig.cmake:607
(message):
A required package was not found
