This commit adds the ability to get a particular resource from an array of resources using the handle_fromBinding intrinsic. The main changes are: 1. Create an array when generating the type. 2. Add capabilities from [SPV_EXT_descriptor_indexing](https://htmlpreview.github.io/?https://github.com/KhronosGroup/SPIRV-Registry/blob/main/extensions/EXT/SPV_EXT_descriptor_indexing.html). We are still missing the ability to declare a runtime array. That will be done in a follow up PR.

This commit adds the ability to get a particular resource from an array
of resources using the handle_fromBinding intrinsic.
The main changes are:
SPV_EXT_descriptor_indexing.
We are still missing the ability to declare a runtime array. That will
be done in a follow up PR.
