* lisp/lib/autoloads.el(doom-autoloads--scan) Remove invoke
`file-truename` of file, keeping symbolic from being converted to a real
path.
* lisp/doom-modules.el(doom-module-from-path) Replace
`file-in-directory-p` with `string-match` to determine the module to
which the file belongs.
Fix: #7821
- Batch more variables in Doom's autoloads files.
- Remove all the register-definition-prefixes calls generated in
autoloads files (for both modules' and packages' autoloads). These
don't serve much purpose, and only incur added cost growing a large
hash table.
