Fix #10243 - studio not saving field properties correctly

[pgorod]

Description

Studio was not saving field properties correctly. This bug has been there for years...

How To Test This

1. Enter Studio
2. Enter a module (such as Cases)
3. Click Fields
4. Enter a field (such as Description) to see its properties:

5. Change one of the properties,
6. Save
7. Exit that screen to the field list
8. Enter the same field again
9. Change a different property
10. Save
11. Exit and go back in
12. Both properties should be retained, instead of the first one you changed being reverted to a default.

The bug caused each subsequent save to throw away the previously saved non-default properties. I guess for a long time people work around this by just changing one property, or repeating the saves when they were mysteriously throw away...

During tests, it might be helpful to keep separate terminals watching these two files:

watch -n 1 cat custom/modules/Cases/Ext/Vardefs/vardefs.ext.php
watch -n 1 cat custom/Extension/modules/Cases/Ext/Vardefs/_override_sugarfield_description.php

Note that the Save action already includes a QR&R, so it is not necessary to do it separately. That's why the contents of those two files will appear in sync after each save.

There's a downside to this PR, although it is really not problematic. Some fields that were not changed, and still have their default values will be included in the saved files. This is because it is not trivial to know if a value is at its default - some of these things depend on configurable settings in other places in the system. So the conservative approach is taken: retain the values that were there when saved, even if it is not clear whether they are defaults and some redundancy occurs.
