Merge #17279: refactor: Remove redundant c_str() calls in formatting

c72906dcc11a73fa06a0adf97557fa756b551bee refactor: Remove redundant c_str() calls in formatting (Wladimir J. van der Laan)

Pull request description:

  Our formatter, tinyformat, *never* needs `c_str()` for strings. Still, many places call it redundantly, resulting in longer code and a slight overhead.

  Remove redundant `c_str()` calls for:

  - `strprintf`
  - `LogPrintf`
  - `tfm::format`

  (also, combined with #17095, I think this improves logging in case of unexpected embedded NULL characters)
