[vim/vim] Remove unnecessary (int) casts before alloc() calls (PR #19889)

[mattn]

alloc() already accepts size_t, so (int) casts on size_t values are redundant and could theoretically cause truncation on values > INT_MAX. Remove the casts and change alloc_cmdbuff() and list_alloc_with_items() signatures from int to size_t to match.

Closes #19888
