  [DAG] SD Pattern Match: Operands patterns with VP Context  (#103308)

Currently, when using a VP match context with `sd_context_match`, only Opcode matching is possible (`m_Opc(Opcode)`).

This PR suggest a way to make patterns with Operands (eg `m_Node`, `m_Add`, ...) works with a VP context.

This PR blocks another PR https://github.com/llvm/llvm-project/pull/102877.
