  [clang] simplify placeholder type deduction for constant template parameters (#160439)

This makes the deduction for dependent types operate in more similar
ways to the non-dependent one, such as when matching template template
parameters, making errors in those generate similar diagnostics to the
non-dependent ones. This also removes some superfluous implicit casts,
simplifying the resulting AST a little bit.
