Validate attributes on function parameters

Entry point function parameter can only have builtin and location
attributes (unless a disable validation attribute is present). Other
functions cannot have any decorations on their parameters.

Fix parameter creation in the CanonicalizeEntryPointIO transform for a
case where it was not stripping attributes that are not valid for
function parameters.
