Fix macro casts in icProfileHeader.h

Fix typos in various macros in icProfileHeader.h for enum bounds checking

[kateniolet]

1. Good catch! Fixed to 'Function' and squashed into the commit.

the change of icMaxCurveElemSignature to icMaxToneFunctionSignature

was because icMaxCurveElemSignature appeared to have been copy-pasted by the original author into the file twice and the second time it was following the icToneFunctionSignature enum - as these are simply macros for referencing the highest value of their respective enums I renamed this second one to fit its conext.

2. I'm not sure I understand the question - compiling is the same as usual, nothing changes there.
