Merge bitcoin/bitcoin#23156: refactor: Remove unused ParsePrechecks and ParseDouble

fa9d72a794 Remove unused ParseDouble and ParsePrechecks (MarcoFalke)
fa3cd28535 refactor: Remove unused ParsePrechecks from ParseIntegral (MarcoFalke)

Pull request description:

  All of the `ParsePrechecks` are already done by `ToIntegral`, so remove them from `ParseIntegral`.

  Also:
  * Remove redundant `{}`. See https://github.com/bitcoin/bitcoin/pull/20457#discussion_r720116866
  * Add missing failing c-string test case
  * Add missing failing test cases for non-int32_t integral types

ACKs for top commit:
  laanwj:
    Code review ACK fa9d72a794, good find on ParseDouble not being used at all, and testing for behavior of embedded NULL characters is always a good thing.

    cr ACK fa9d72a794
