Problem: vim9: clean up from v9.0.1955
Solution: Fix a few remaining issues, improve error message
- Use `cl_exec`, the executing class, to check permissions in `get_lval()`.
- Handle lockvar of script variable from class.
- Add 'in class "Xxx"' to e_cannot_access_private_variable_str.

Problem: Vim9: lockvar issues with objects/classes
Solution: fix `get_lhs()` object/class access and avoid `SEGV`,
make error messages more accurate.
- `get_lval()` detects/returns object/class access
- `compile_lock_unlock()` generate code for bare static and obj_arg access
- `do_lock_var()` check lval for `ll_object`/`ll_class` and fail if so.
Details:
- Add `ll_object`/`ll_class`/`ll_oi` to `lval_T`.
- Add `lockunlock_T` to `isn_T` for `is_arg` to specify handling of `lval_root` in `get_lval()`.
- In `get_lval()`, fill in `ll_object`/`ll_class`/`ll_oi` as needed; when no `[idx] or .key`, check lval_root on the way out.
- In `do_lock_var()` check for `ll_object`/`ll_class`; also bullet proof ll_dict case
and give `Dictionay required` if problem. (not needed to avoid lockvar crash anymore)
- In `compile_lock_unlock()` compile for the class variable and func arg cases.

Problem: No type checking in interfaces
Solution: Implement member type check in vim9 interfaces
Most of the code is a small refactoring to allow the use of a where_T
for signaling the type mismatch, the type checking itself is pretty
simple.
Improve where_T error reports
Let the caller explicitly define the kind of location it's referring to
and free the WT_ARGUMENT enum from its catch-all role.
Implement type checking for interface methods
Follows closely the logic used for type-checking the members.

Problem: Looping over list of lists and changing the list contents works in
Vim9 script, not in a compiled function.
Solution: Mark the loop variable final instead of const. (closes#11347)
Problem: Closure in compiled function gets same variable in block.
Solution: At the end of a block to not always reset the variable count.
(issue #11094)
Problem: In a :def function all closures in a loop get the same variables.
Solution: Use a separate list of variables for LOADOUTER and STOREOUTER.
Not copied at end of loop yet.
Problem: In a :def function all closures in a loop get the same variables.
Solution: When in a loop and a closure refers to a variable declared in the
loop, prepare for making a copy of variables for each closure.
Problem: The :defer command does not check the function argument count and
types.
Solution: Check the function arguments when adding a deferred function.
Problem: Vim9: return type "any" is sometimes changed to first returned
type. (Virginia Senioria)
Solution: Do not change the return type if declared as "any". (closes#9949)
