runtime(java): Manage byte limits for variable-width lookbehind assertions

Browse Source 
Raise the byte limits from 80 to 120 for "javaFuncDef" and
"java*CommentTitle"; and support selecting other arbitrary
values with
------------------------------------------------------------
	let g:java_lookbehind_byte_counts = {
		\ 'javaMarkdownCommentTitle': 240,
	\ }
------------------------------------------------------------

for related groups of syntax definitions, referring to their
names with dictionary keys.

Over-80-Byte-Limit Lookbehind Examples:
