[v3dv/BCM2711] Support for shaderSampledImageArrayDynamicIndexing

This is more of a question than a bug report, hope that's ok!

I'm running a Broadcom BCM2711 (RPi4b), and had intended to use texture arrays in shaders for a certain usecase. This works fine on Nvidia/AMD on x64, however on this specific platform, it doesnt seem to work. I think it is because vkGetPhysicalDeviceFeatures returns back that the shaderSampledImageArrayDynamicIndexing feature isn't enabled.

Is it realistically possible for the given hardware to support this feature? Will Mesa ever support it? How much work is involved in getting this supported?

I've never dabbled this low-level in graphics programming before, so I really have no idea what to expect right now.

Many thanks in advance,
