conf.py: improve SearchEnglish to handle terms with dotsHEADmaster

While search queries already handled words with hyphens correctly, they
did not do so for words with dots.

To fix this, we

- enhance the word tokenizer to treat both dots ('.') and hyphens ('-')
  as valid characters within words.
  (For robustness, explicitly exclude dots/hyphens at the start or end
  of a word from indexing.)
- adjust query processing to avoid splitting on dots in search input

This allows search queries to correctly match terms such as
'local.conf', 'site.conf', and similar ones now.

Fixes: [YOCTO #14534]
