BACKPORT: msm: kgsl: Add support for KGSL_PROP_VK_DEVICE_ID

Usermode driver expect vulkan device id info from kernel. Add new KGSL_PROP_VK_DEVICE_ID property support to provide vk-device-id information. Change-Id: Ib4f6872fcd3a956caeaad6e7c9f534d7c8e87305 Signed-off-by: Hareesh Gundu <[email protected]> Signed-off-by: UtsavBalar1231 <[email protected]>
