Add elementwise mappable variation for rlwe_encode

This change adds a new ElementwiseByOperandOpInterface method that allows an op to specify which dimensions of a tensor-typed operand should be mapped over. This is necessary to support having an elementwise op like lwe.rlwe_encode, whose input is a tensor<k x slots> and whose output is a tensor<k x lwe.lwe_plaintext<...>>. This is needed in turn because server-side secret.conceal lowers to an elementwise trivial_encrypt, which lowers to an elementwise encode + encrypt.

The verifier is updated to ensure that the "mapped shape" (subset of dimensions specified by the interface as mappable) aligns across operands and the output.

Then the ElementwiseToAffine pass is updated to use this interface to support lwe.rlwe_encode.
