Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
vim/vim#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.

Problem: Vim9: a failing debug expression aborts script sourcing.
Solution: Do not let expression failure abort script sourcing. (closesvim/vim#8848)

Vim9script is N/A, exclude Test_Debugger_breakadd_expr.
Move debuggy struct to before generated header inclusion so
eval_expr_restore prototype works.
Add CheckRunVimInTerminal to Test_Debugger_breakadd.
Cherry-pick Test_Debugger_breakadd changes from v8.2.1440, v8.2.1736.
Problem: Vim script debugger functionality needs cleanup.
Solution: Move debugger code to a separate file. Add more tests. (Yegappan
Lakshmanan, closesvim/vim#4285)

Good to have for eval_expr_restore in v8.2.3417.
Doesn't actually add any tests.
