[CLI Refresh] Consistent payload input options across all commands

[dandavison]

Workflow input payload supports options including

  -i, --input stringArray              Input value (default JSON unless --input-payload-meta is non-JSON encoding). Can be given multiple times for multiple arguments. Cannot be combined with --input-file.
      --input-base64                   If set, assumes --input or --input-file are base64 encoded and attempts to decode.
      --input-file stringArray         Reads a file as the input (JSON by default unless --input-payload-meta is non-JSON encoding). Can be given multiple times for multiple arguments. Cannot be combined with --input.
      --input-meta stringArray         Metadata for the input payload. Expected as key=value. If key is encoding, overrides the default of json/plain.

Extend this to make payload functionality uniform across other payloads inputs such as Activity result, Activity failure detail.
