runtime(java): Improve the matching of contextual keywords

Browse Source 
- Recognise a _record_ contextual keyword.
- Recognise _non-sealed_, _sealed_, and _permits_ contextual
  keywords.
- Admit _$_ to keyword characters.
- Group _abstract_, _final_, _default_, _(non-)sealed_
  (apart from _(non-)sealed_, the incompossibility of these
  modifiers calls for attention).
- Remove another _synchronized_ keyword redefinition.

I have also replaced a function with an expression.  Before
patch 8.1.0515, it should have been declared :function! to
work with repeatable script sourcing; there is less to worry
about with an expression.
