patch 8.2.5106: default cmdwin mappings are re-mappable

Commit: https://github.com/vim/vim/commit/44068e97dbd8fc8ebd93113e436a1e37a6bff52c
Author: zeertzjq <zeertzjq@outlook.com>

    patch 8.2.5106: default cmdwin mappings are re-mappable

    Problem:    Default cmdwin mappings are re-mappable.
    Solution:   Make the default mappings not re-mappable. (closes https://github.com/vim/vim/issues/10580)  Use
                symbols for the first do_map() argument.
