runtime(java): Recognise non-ASCII identifiers (#14543)
* runtime(java): Recognise non-ASCII identifiers
Also:
- Remove the already commented out and less general in its
definition javaFuncDef alternative.
- Stop recognising some bespoke {p,trace} debugging API.
Non-ASCII identifiers have been supported from the outset
of the Java language.
> An _identifier_ is an unlimited-length sequence of _Java
> letters_ and _Java digits_, the first of which must be a
> Java letter. An identifier cannot have the same spelling
> (Unicode character sequence) as a keyword . . . Boolean
> literal . . . or the null literal . . .
> . . . . . . . .
> Letters and digits may be drawn from the entire Unicode
> character set . . .
> . . . . . . . .
> A Java letter is a character for which the method
> Character.isJavaLetter . . . returns true. A Java
> letter-or-digit is a character for which the method
> Character.isJavaLetterOrDigit . . . returns true.
> . . . . . . . .
> The Java letters include . . . for historical reasons, the
> ASCII underscore (_) . . . and dollar sign ($) . . .
(Separate syntax tests will be written when particular parts
now touched will have been further improved.)
