android: enable VK_ANDROID_native_buffer
Patch changes entrypoints generator to not skip this extension even
though it is set as disabled in the xml. We also need compilation
flag VK_USE_PLATFORM_ANDROID_KHR to be enabled.
It looks like this extension got disabled in commit 69f447553c.
v2: just remove the whole 'supported' attrib check + remove
vk_icd.h compilation fix (fix in VulkanHeaders instead)
