writing and sourcing a file (Yegappan Lakshmanan)

Problem: Vim9: restrict access to static vars and methods
Solution: Class members are accesible only from the class where they are
defined.
Based on the #13004 discussion, the following changes are made:
1) Static variables and methods are accessible only using the class
name and inside the class where they are defined.
2) Static variables and methods can be used without the class name in
the class where they are defined.
3) Static variables of a super class are not copied to the sub class.
4) A sub class can declare a class variable with the same name as the
super class.
5) When a method or member is found during compilation, use more
specific error messages.
This aligns the Vim9 class variable/method implementation with the Dart
implementation.
Also while at it, ignore duplicate class and object methods.
The access level of an object method can however be changed in a
subclass.
For the tests, use the new CheckSourceFailure() function instead of the
CheckScriptFailure() function in the tests.

Problem: Vim9: finding global function without g: prefix but not finding
global variable is inconsistent.
Solution: Require using g: for a global function. Change the vim9.vim
script into a Vim9 script with exports. Fix that import in legacy
script does not work.
Problem: Vim9: inconsistent arguments for test functions.
Solution: When :def function and script have different arguments use a list
with two items instead of a separate function.
Problem: Vim9: not enough tests run with Vim9.
Solution: Run a few more tests in Vim9 script and :def function. Fix that
items(), keys() and values9) return zero for a NULL dict.
Make join() return an empty string for a NULL list. Make sort()
return an empty list for a NULL list.
Problem: Vim9: white space checks are only done for a :def function.
Solution: Also do checks at the script level. Adjust the name of a few
error messages.
Problem: Vim9: error for list index uses wrong line number.
Solution: Set source line number. (closes#6724) Add a way to assert the
line number of the error with assert_fails().
Problem: Vim9: using a discovery phase doesn't work well.
Solution: Remove the discovery phase, instead compile a function only when
it is used. Add :defcompile to compile def functions earlier.
