Feature Request: Support Custom Vulkan Driver Loading on Android (Mesa Turnip for ParaLLEl N64)

Please add support in RetroArch Android to load a custom Adreno Driver (e.g. Mesa Turnip) from user storage. This would allow users to bypass limited Adreno system drivers and enable full functionality in cores like ParaLLEl (with ParaLLEl GFX + RSP Plugins).

Problem:

On Adreno GPUs (e.g. Adreno 650), using ParaLLEl (with ParaLLEl GFX + RSP Plugins) results in a black screen with only "ERR" shown. Logs confirm missing Vulkan features:

VK_KHR_8bit_storage

VK_KHR_16bit_storage

VK_EXT_external_memory_host

These are required for ParaLLEl (with ParaLLEl GFX + RSP Plugins) to boot and render.

Solution:

Add support for loading custom Vulkan drivers from internal storage:

Accept .zip or folder with Community Drivers

Path-based override (e.g. /sdcard/RetroArch/mesa/)

Benefit:

ParaLLEl (with ParaLLEl GFX + RSP Plugins) becomes usable on Adreno devices

Matches Vulkan flexibility in other Android emulators

EDIT: I contacted K11MCH1 from Adrenotools and he said VK_KHR_8bit_storage and VK_KHR_16bit_storage were already implemented.

The issue names no files, tests, or entry points. Start by locating RetroArch's Android Vulkan driver-loading path and review the linked libadrenotools source. Done means defining and validating a supported custom-driver source, path override, and loading behavior that enables the required Vulkan features.
