Test updates - #17677

Problem:  tests: still some ANSI escape sequences in test messages output
Solution: update the cleanup regexp to also handle those ANSI escape
          sequences: `<esc>|2h` and `<esc>|31H` like in this log output:

```
2025-07-05T20:02:47.6350409Z <esc>|2hExecuted 171 tests in   4.739708 seconds<esc>|31H
```

Problem:  tests: too many imports in the test suite
Solution: Clean up the imported scripts

Most tests make use of check.vim, so let's just source it once in
runtest.vim instead of having each test manually source it.

runtest.vim already sources shared.vim, which again sources
view_util.vim, so we don't need to source those two common
dependencies in all the other tests

And then check.vim sources term_util.vim already, so we can in addition
drop sourcing it explicitly in each single test script.

Note: test_expand_func.vim had to be updated to account for the changed
number of sourced files.

And finally check.vim uses line-continuation so let's also explicitly
enable line continuation via the 'cpo' option value.

patch 9.1.1518: getcompletiontype() may crash

Problem:  getcompletiontype() crashes when no completion is available
          (after v9.1.1509).

patch 9.1.1519: tests: Test_termdebug_decimal_breakpoints() may fail

Problem:  Test_termdebug_decimal_breakpoints() fails with List index out
          of range, because when adding the second breakpoint, the
          cursor is still on the very first line (a header include line)
          and therefore gdb refuses to set the breakpoint with:
          `msg="No compiled code for line 1 in file XTD_decimal.c"`
Solution: Run the program, so that it will break at the very first
          defined breakpoint and then once we are in the program,
          set further breakpoints

patch 9.1.1520: completion: search completion doesn't handle 'smartcase' well

Problem:  When using `/` or `?` in command-line mode with 'ignorecase' and
          'smartcase' enabled, the completion menu could show items that
          don't actually match any text in the buffer due to case mismatches

Solution: Instead of validating menu items only against the user-typed
          pattern, the new logic also checks whether the completed item
          matches actual buffer content. If needed, it retries the match
          using a lowercased version of the candidate, respecting
          smartcase semantics.

patch 9.1.1521: completion: pum does not reset scroll pos on reopen with 'noselect'

Problem:  When 'wildmode' is set to include "noselect", the popup menu (pum)
          incorrectly retained its scroll position when reopened. This
          meant that after scrolling down through the menu with `<C-n>`,
          reopening the menu (e.g., by retyping the command and
          triggering completion again) would show the menu starting from
          the previously scrolled position, rather than from the top.
          This could confuse users, as the first visible item would not
          be the first actual match in the list.

Solution: Ensure that the popup menu resets its scroll position to the
          top when reopened (Girish Palya).

patch 9.1.1525: tests: testdir/ is a bit messy

Problem:  tests: testdir is a bit messy
Solution: move test scripts into testdir/util/ directory

src/testdir/ has become a dumping ground mixing test cases with utility
functions. Let's fix this by moving all utility functions into the
testdir/util/ directory

Also a few related changes had to be done:
- Update Filelist
- update README.txt and mention the new directory layout
- fix shadowbuild by linking the util directory into the shadow dir

runtime(netrw): restore blank line cleanup after file listing

Problem:  v182 refactoring removed blank line cleanup (g/^$/d) from
          s:LocalListing(), causing empty lines between directories
          and files.
Solution: Add the missing cleanup after append() in s:PerformListing()
          (uma-chan).
