Android build fixes (#1156)

* Add gradle build scripts to more examples

* Fix building graphicspipelinelibrary example on android

* Fix tinygltf dependencies

hostimagecopy uses tinygltf but didn't depend on it, while meshshader doesn't use it.

* Load more Vulkan functions on Android

The sparse functions are used by texturesparseresidency, while the begin/end rendering functions are used by trianglevulkan13.
