NormalizeWhitespace should put * next to the type rather than the identifier

[AArnott]

Version Used: Microsoft.CodeAnalysis.CSharp 3.8.0

Steps to Reproduce:

Use NormalizeWhitespace on a VariableDeclarationSyntax containing a PointerTypeSyntax

Expected Behavior:

The output should put the asterisk on the type, for example:

int* p;
int* p1, p2;

Actual Behavior:

The output puts the asterisk on the first identifier:

int *p;
int *p1, p2;

Besides just the nit that the asterisk applies to the type, it honestly makes p1 look like a pointer where p2 does not look like a pointer. But when the asterisk is on the type itself, it's much more apparent how the compiler will always interpret it.

Moving back to compilers, as this regards NormalizeWhitespace as opposed to the formatter APIs.
