BaseTools: add ASSERT checker for array buffer in fdf and command line
For structure PCD in fdf file and command line,
1. use compiler time assert to check the array index, report error
if array index exceeds the array number.
2. use compiler time assert to check the array size, report error
if the user declared size in header file is smaller than the user
used in fdf file and command line.
