CI: add/extend curl binary info, VS2010 32-bit, misc improvements

- fix `find` commands to not miss items.

- call `file` on the built files in `curl -V` steps.
  To give more feedback on what was built.

- add `curl info` step for cross-jobs that can't do a `curl -V`.
  It lists the files built and calls `file` on them.

- appveyor: make a VS2010 32-bit to match the VS2008 job it replaced.
  Follow-up to d34aeecb08 #15934

- GHA/windows: drop the word "old" from standalone mingw-w64 jobs to not
  conflate it with "old mingw" we no longer support (while also keeping
  it short).

Cherry-picked from #15975
Closes #16001
