fix(path): nvim_get_runtime_file fails on DOS 8.3 filename #40144

Browse Source 
Problem:
stdpath() may return a DOS 8.3 "shortened" filename, because Windows
truncates some long usernames into `6ch~N` names. Then features such
as `nvim_get_runtime_file` fail to find the file.                                         
                                                                                                                    
Analysis:
When expanding an 8.3 filename path like `C:/Users/ADMINI~1/AppData/*`,
we treat `~` as a special character and first check whether a directory
named `ADMINI~1` exists under `Users`. Since no such directory actually
exists, the expansion fails.                                                                                                    
                                                                                                                    
Solution:
Treat `~` as a literal character in `do_path_expand`. Since the `~/`
case is already handled in `gen_expand_wildcards`, any remaining `~` is
just a literal character and will later be escaped to `\~` by
`file_pat_to_reg_pat` if needed.
