Use internal wcstof instead of system wcstod in formcalc lexer
This CL switches the usage of wcstod to use the FXSYS_wcstof to determine if a given string is a valid floating point number. Using the internal method makes linux slightly slower (10's of ms) makes mac a lot faster 900ms to 60ms for the test case in the bug. The FXSYS_wcstof method has been extended to handle the parsing of float exponents. Unittests were added for FXSYS_wcstof.
