vim-patch:8.2.4749: <script> is not expanded in autocmd context

Problem:    <script> is not expanded in autocmd context.
Solution:   Add the context to the pattern struct. (closes vim/vim#10144)
            Rename AutoPatCmd to AutoPatCmd_T.
https://github.com/vim/vim/commit/eca7c60d68e63001dbe3c8e5d240b0895e607fc3

Omit AutoPatCmd -> AutoPatCmd_T rename as it is inconsistent.
Use `.sn_name` instead of `->sn_name` as v8.2.0154 hasn't been ported.
Omit acp_script_stx(), use member directly.
