f08b4fff - [HLSL] Allow __builtin_hlsl_resource_getpointer to take no indices (#195151)

[HLSL] Allow __builtin_hlsl_resource_getpointer to take no indices (#195151) In preperation for adding ConstnatBuffer<T>, we will need to be able to access the base pointer for the data constat buffer resource handle is pointingto to. This is done by: 1. Making the index operand in __builtin_hlsl_resource_getpointer optional. 2. Modifing the codegen for __builtin_hlsl_resource_getpointer to emit a call to resource.getbasepointer when no index is provided. 3. Add the resource.getbasepointer for the dx and spv targets. Another issue is that the address space for the pointer returned by __builtin_hlsl_resource_getpointer is not always hlsl_device any more. Changes are made to get the correct address space based on the resource class of the handle. Note that we cannot implement codegen for __builtin_hlsl_resource_getpointer directly. The tests for the codegen changes will be in a follow up PR that add ConstnatBuffer<T>.
