  [VPlan] Thread scalar types through VPWiden(Cast)Recipe. (NFC) (#199572)

Update VPWidenRecipe and VPWidenCastRecipe to populate
VPSingleDefValue's
scalar type. For all VPWidenRecipe opcodes, the scalar type is determine
from the operands, via computeScalarTypeForInstruction (from
https://github.com/llvm/llvm-project/pull/199378).
For cast, the type must be provided explicitly.

Depends on https://github.com/llvm/llvm-project/pull/199378
