text: Title: Support argument conversion with `Should Be Equal`
  Body: to compare bytes returned from keyword it is necessary to create variable using Convert To Bytes and then compare using `Should be equal`
  
  ```robot
  *** Keywords ***
  Keyword returning bytes
      ${return} =    Convert To Bytes    \x1\x2
      [Return]  ${return}
  
  *** Test Cases ***
  Test
      ${bytes_result} =    Keyword returning bytes
      ${expected_result} =    Convert To Bytes    \x1\x2\x3
      Should be Equal     ${bytes_result}    ${expected_result}
  ```
  it would be easier to have possibility to have direct way to compare it directly.
  It could be done by adding `Should be Equal as Bytes` similar to `Should be Equal as Numbers` or as @pekkaklarck suggested in #5041 by adding `type` argument to `Should be Equal` -> `type=bytes`
