Optimize SA1141

[sharwell]

• Avoid all work on compilations that don't support tuples (not a common case)
• Check identifier names before calling GetSymbolInfo

This is a partial resolution of the issue that led to #3609. Note that the new behavior for handling ValueTuple.Create will not work correctly in cases where users have a using alias directive like the following:

using VT = System.ValueTuple;

Good catch with these missing test classes. I assume it was a mistake to not add them earlier. Would be good to have automated checks for things like this.
