Pull request description:

  This is a component of [removing libevent as a dependency of the project](https://github.com/bitcoin/bitcoin/issues/31194). It is the first six commits of #32061 and provides a string-parsing utility (`LineReader`) that is also consumed by #34158.

  These are the functions that are added / updated for HTTP and Torcontrol:

  - `GetBindAddress()`: Given a socket, provides the bound address as a CService. Currently used by p2p but moved from `net` to `netbase` so other modules can call it.
  - `ToIntegral()`: Already used to parse numbers from strings, added new argument `base = 10` so it can also be used to parse hexadecimal integers. HTTP chunked transfer-encoding uses hex-encoded integers to specify payload size: https://datatracker.ietf.org/doc/html/rfc7230.html#section-4.1
  - `AsciiCaseInsensitive` comparators: Needed to store HTTP headers in an `unordered_map`. Headers are key-value pairs that are parsed with case-insensitive keys: https://httpwg.org/specs/rfc9110.html#rfc.section.5.1
  - `FormatRFC1123DateTime()`: The required datetime format for HTTP headers (e.g. `Fri, 31 May 2024 19:18:04 GMT`)
  - `LineReader`: Fields in HTTP requests are newline-terminated. This struct is given an input buffer and provides methods to read lines as strings.
