This patch adds a utility class that will be used in subsequent patches for parsing the function/callsite attributes and determining whether changes to PSTATE.SM are needed, or whether a lazy-save mechanism is required. It also implements some of the restrictions on the SME attributes in the IR Verifier pass. More details about the SME attributes and design can be found in D131562.
