GL: Remove parallel compile/link without driver support This feature was practically disabled everywhere due to various bugs, and is complicating the code. In effect, the code was always spawning a thread for the compilation and link jobs, immediately fail it (due to a workaround), then do the job when compile/link is resolved (much closer to draw time). This leads to bad user experience, but also is racy because the shaders may get recompiled in the meantime and there is little the GL backend could do to stop that (efficiently). After this change, parallel compile/link is either done by the driver (if supported), or it isn't done. This is a partial revert of a100d8f471f79b9f88d387164992cc5bd9c6ee9f.
