fix(nodemcu-32s): Fix Upload Speed menu on Windows (#10012)

* fix(nodemcu-32s): Fix Upload Speed menu on Windows

The board definition had 460800 as default upload speed, but that is invalid on Windows, so the menu did not show. This change puts 115200 as default, which will make the menu appear

* fix(board): Make build.board uppercase
