Resctrl's architecture code gets to specify a function pointer that is used when parsing schema entries. This is expected to be one of two helpers from the filesystem code. Setting this function pointer allows the architecture code to change the ABI resctrl presents to user-space, and forces resctrl to expose these helpers. Instead, add a schema format enum to choose which schema parser to use. This allows the helpers to be made static and the structs used for passing arguments moved out of shared headers.
