vcl: refactor ErrorHandler functions
Current, HandleError_Impl is called on by GetErrorString, and
HandleError_Impl also creates the error string. However, when
you look at what each function does, HandleError_Impl has been
imbued with some extraneous parameters:
1. bJustCreateString, and
2. rError
bJustCreateString is unnecessary, in fact it just mutates
HandleError to create the string, which is not really the core
purpose of this function. In fact, the string should be created
when we get the string from the error ID (GetErrorString), and
in fact the error handler function should call on GetErrorString
and not the other way around!
This has the happy side effect of vastly simplifying this code,
and allows each of the functions only do the thing they are
meant to do, and we no longer need these extraneous parameters
which just cause problems for code readibility. On to of this,
by simplifying the HandleError_Impl function, we just move the
code into the public HandleError function because these
parameters aren't necessary any more.
