Hi,

Now for some riscv64 real hardware, like licheepi4a/versionfive2(vf2),
there is only gles support for display. So if we use firefox on these
hardwares, we can not use hardware webrender only software webrender
works.

I just built firefox based on 119.0.1-1 with gles support then can use
hardware webrender on licheepi4a.

In the meantime, I've sent this report upstream also. see:
https://bugzilla.mozilla.org/show_bug.cgi?id=1865601

If upstream takes too long time to response with it, hoping the support
can be uploaded on the next upload so that to improve the the user
experience on firefox for riscv64 platform.

Please let me know any issues, thanks.
