vim-patch:8.2.0855: GUI tests fail because the test doesn't use a modifier
Problem: GUI tests fail because the test doesn't use a modifier.
Solution: Add "\{xxx}" to be able to encode a modifier.
https://github.com/vim/vim/commit/ebe9d34aa07037cff2188a8dd424ee1f59cbb0bf
Change macros to enums to use them in unit tests.

@@ -1325,6 +1325,9 @@ A string constant accepts these special characters:
To use the double quote character it must be escaped: "<M-\">".
Don't use <Char-xxxx> to get a UTF-8 character, use \uxxxx as
mentioned above.
+\{xxx} like \<xxx> but prepends a modifier instead of including it in the
+ character. E.g. "\<C-w>" is one character 0x17 while "\{C-w}" is four
+ bytes: 3 for the CTRL modifier and then character "W".
Note that "\xff" is stored as the byte 255, which may be invalid in some
encodings. Use "\u00ff" to store character 255 correctly as UTF-8.
