BaseTools: add ASSERT checker for array buffer value assignment.

V3:
Update the error message for array checker.
V2:
1. Add comments for each ASSERT.
2. ASSERT need to skip the case of array size of array as zero. For
example, TestArray[] in struct in header file.
V1:
For structure PCD,
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
defined in DEC/DSC file.
