transform: Operation based matching from spec for patching

[kumarak]

PR is dependent on #94 and include the changes.

The changes perform operation based matching from the spec and perform patching operation. The Operation matching only support BeforeApply mode at the moment.

An example spec for matching cir.call operation to spo2_lookup can be written as below. It will check for all cir.call operation making a call to symbol_name spo2_lookup and should be called in specific function context with pattern "/.*measurement.*/.

arch: "ARM:LE:32"
patches:
  - name: "apply_before_spo2_lookup_operation"
    match:
      name: "cir.call"
      kind: "operation"
      function_context:
        - name: "/.*measurement.*/"  # Functions containing "measurement"
        - name: "/.*update.*/"       # Functions containing "update"
      operand_matches:
        - index: 0  # First argument to the called function
          name: "var6"
          type: "!cir.float"
      symbol_matches:
        - name: "spo2_lookup"  # The function being called
    patch:
      mode: "ApplyBefore"
      patch_file: "patch_spo2_lookup.c"
      patch_function: "patch::before::spo2_lookup"
      arguments:
        - "var6"
    exclude:
      - ""
