Remove unnecessary type info calls

This pull request has two purposes:

1) In ROOT6, ROOT does not provide type_info information for non-class types, such as enums, pointers, and C-Style arrays.  This currently can cause TypeWithDict::typeInfo() to return incorrect information in the ROOT6 IB.  The first step to fixing this problem is to remove unnecessary calls to TypeWithDict::typeInfo().  This pull request does this in the framework and in
CommonTools/Utils/src/AnyMethodArgument.h. Since the changed code works equally well in ROOT5, this is being requested in the main 7_4_X branch (ROOT5) for code commonality.

2) I happened to notice that I had extensively edited several other source files in ComonTools/Utils in the ROOT6 branch to make them more readable (non-substantive formatting changes).  These changes should have been made in the main branch as well for code commonality.  This pull request makes the same changes in the main 7_4_X branch for code commonality with the ROOT6 IB.  All the changes in CommonTools/Utils, except for those in AnyMethodArgument.h, are essentially no-ops.

All unit tests in the affected packages pass and the short relval matrix tests still pass with these changes.

I request that this pull request not be merged into the 7_4_X_ROOT6 branch, because these changes will be made there independently.  This is not critical, because I can clean things up if merging this causes any problems in the 7_4_X_ROOT6 branch.
