John Wigg ee8b3bef2d Limit undo stack size 
The stack size of the undo history of a TextEdit was not limited leading
to potential memory leaks when doing lots of operations on a TextEdit.

This commit adds the option gui/common/text_edit_undo_stack_max_size
to the project settings. The first element of the undo stack is popped
if the stack's size exceeds this value ensuring limited memory usage.

The default stack size setting is 1024.

Fixes #37838.
