cmake: Optimize Android VVL download logic

Browse Source 
Improve the Vulkan Validation Layer (VVL) download logic for Android by checking
for the final library file instead of just the zip archive. This prevents
unnecessary re-downloads and extractions when the library is already in place.

The check now looks for libVkLayer_khronos_validation.so in the final
destination path before attempting to download and extract the archive.
