Currently ExtBinary format doesn't support multiple sections with the same type in the profile. We add the support in this patch. Previously we use the section type to identify a section uniquely. Now we introduces a LayoutIndex in the SecHdrTable and use the LayoutIndex to locate the target section. The allocations of NameTable and FuncOffsetTable are adjusted accordingly.
