  [LV] Refactor vector function variant selection to prepare for uniform args (#68879)

Parameters marked as uniform take a scalar value, assuming the value is
invariant in the scalar loop. In order to support this, we need to stop
asking for a vector function variant with a default shape assuming that all
arguments will become vector arguments, and instead consider all available
variants and their parameter types.
