runtime(vim): Distinguish Vim9 builtin object methods from namesake builtin functions (#14348)

Browse Source 
Currently, the overriding object method definitions are
matched as vimFunctionError (:help builtin-object-methods,
v9.1.0148).

For example:
------------------------------------------------------------
vim9script

class Test
	def string(): string
		return "Test"
	enddef
endclass

echo string(Test.new()) == Test.new().string()
------------------------------------------------------------

Instead, let's introduce a new syntax group vimMethodName
and make these methods its members.  In order to emphasise
the link between the overriding methods and the overridden
functions for highlighting, vimMethodName is linked by
default to vimFuncName.
