[3.8] gh-103142: Upgrade binary builds and CI to OpenSSL 1.1.1u (GH-105174) (GH-105200) (GH-105205) (#105370)

Upgrade builds to OpenSSL 1.1.1u.

Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9.

Manual edits to the _ssl_data_300.h file prevent it from removing any
existing definitions in case those exist in some peoples builds and were
important (avoiding regressions during backporting).

(cherry picked from commit ede89af)
(cherry picked from commit e15de14c16ce98e773c31607bd70ee911e4ac073)
