Problem: compiler warnings with clang-17
Solution: Fix function prototypes and function pointer
fix: clang compilation warnings with -Wstrict-prototypes
Change fixes this kind of compilation warnings with clang:
```
proto/if_python3.pro:13:20: warning: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]
13 | int python3_version();
| ^
| void
```

Problem: Need more accurate profiling
Solution: Improve profiling results
closes: #12192
Reduce overhead of checking if a function should be profiled,
by caching results of checking (which are done with regexp).
Cache uf_hash for uf_name in ufunc_T.
Cache cleared when regexps are changed.
Break at first match for has_profiling lookup.

Problem: RedrawingDisabled not used consistently.
Solution: Avoid RedrawingDisabled going negative. Set RedrawingDisabled in
win_split_ins(). (closes#11961)
Problem: "clear" macros are not always used.
Solution: Use ALLOC_ONE, VIM_CLEAR, CLEAR_POINTER and CLEAR_FIELD in more
places. (Yegappan Lakshmanan, closes#12104)
Problem: Vim9: expression breakpoint not checked in :def function.
Solution: Always compile a function for debugging if there is an expression
breakpoint. (closes#8803)
Problem: Vim9: compiled functions are not profiled.
Solution: Add initial changes to profile compiled functions. Fix that a
script-local function was hard to debug.
Problem: Execution stack is incomplete and inefficient.
Solution: Introduce a proper execution stack and use it instead of
sourcing_name/sourcing_lnum. Create a string only when used.
Problem: Expression type is used inconsistently.
Solution: Add "ETYPE_IS" and "ETYPE_ISNOT" as separate enum values. Rename
"TYPE_" to "ETYPE_" to avoid confusion.
Problem: Using "int" for alloc() often results in compiler warnings.
Solution: Use "size_t" and remove type casts. Remove alloc_check(), Vim
only works with 32 bit ints anyway.
Problem: Vim script debugger functionality needs cleanup.
Solution: Move debugger code to a separate file. Add more tests. (Yegappan
Lakshmanan, closes#4285)
