Problem:
There are three different ways of marking an option as hidden, `enable_if
= false`, `hidden = true` and `immutable = true`. These also have different
behaviors. Options hidden with `enable_if = false` can't have their value
fetched using Vim script or the API, but options hidden with `hidden = true` or
`immutable = true` can. On the other hand, options with `hidden = true` do not
error when trying to set their value, but options with `immutable = true` do.
Solution:
Remove `enable_if = false`, remove the `hidden` property for options, and use
`immutable = true` to mark an option as hidden instead. Also make hidden option
variable pointers always point to the default value, which allows fetching the
value of every hidden option using Vim script and the API. This does also mean
that trying to set a hidden option will now give an error instead of just being
ignored.
Problem: zip-plugin has problems with special characters
(user202729)
Solution: escape '*?[\' on Unix and handle those chars
a bit differently on MS-Windows, add a test, check
before overwriting files
runtime(zip): small fixes for zip plugin
This does the following:
- verify the unzip plugin is executable when loading the autoload plugin
- handle extracting file names with '[*?\' in its name correctly by
escaping those characters for the unzip command (and handle those
characters a bit differently on MS-Windows, since the quoting is different)
- verify, that the extract plugin is not overwriting a file (could cause
a hang, because unzip asking for confirmation)
- add a test zip file which contains those special file names

Problem: zip plugin has no way to set/restore option values
Solution: Add the SetSaneOpts() and RestoreOpts() functions,
so options that cause issues are set to sane values
and restored back to their initial values later on.
(this affects the 'shellslash' option on windows, which also
changes how the shellescape() function works)

Problem: Cannot browse zipfiles with the unzip program found
on FreeBSD.
Solution: Adjust command arguments.
Unzip found on FreeBSD complain about missing argument with the
zipinfo modifier '-Z -1'. Joining arguments seems to work
for both implementations.
Also change `:sil!` to `:sil` so that error messages are properly
reported (per review of Christian Brabandt).

Problem: After 6f1cbfc9ab fnameescape()
is no longer called on the name of the file to be extracted.
However, while spaces indeed don't need to be escaped, unzip
treats '[' as a wildcard character, so it need to be escaped.
Solution: Escape '[' on both MS-Windows and Unix.
From the docs it seems '*' and '?' also need escaping, but they seem to
actually work without escaping.

This change does the following 3 things:
1) non need to quote the file to be extracted
The zipfile plugin used to quote and fnameescape() the path to the
file to be extracted. However testing with unzip showed, that while this
works on Linux on Windows you shall not escape the blanks in filenames.
As long as the pathname is properly quoted, this words on Linux and
Windows.
2) reset shellslash (MS-Windows only)
When shellslash is set, filenames to the zip archive will be forward
quoted. However since the filename is eventually handed over to the
unzip command, we need to make sure to use native paths so that the
command will understand what file to open. Therefore, if shellslash is
set (and the shell is cmd.exe), replace any forward slashes by the
expected backslashes
3) style:
Use tabs for the Header, remove a few comments in the s:Escape() and
zip#read() functions

runtime(dist): centralize safe executable check and add vim library (vim/vim#13413)
Follow up to 816fbcc26 (patch 9.0.1833: [security] runtime file fixes,
2023-08-31) and f7ac0ef50 (runtime: don't execute external commands when
loading ftplugins, 2023-09-06).
This puts the logic for safe executable checks in a single place, by introducing
a central vim library, so all filetypes benefit from consistency.
Notable changes:
- dist#vim because the (autoload) namespace for a new runtime support
library. Supporting functions should get documentation. It might make
life easier for NeoVim devs to make the documentation a new file
rather than cram it into existing files, though we may want
cross-references to it somewhere…
- The gzip and zip plugins need to be opted into by enabling execution
of those programs (or the global plugin_exec). This needs
documentation or discussion.
- This fixes a bug in the zig plugin: code setting s:tmp_cwd was removed
in f7ac0ef50 (runtime: don't execute external commands when loading
ftplugins, 2023-09-06), but the variable was still referenced. Since
the new function takes care of that automatically, the variable is no
longer needed.

runtime(ftplugin): allow to exec if curdir is in PATH
In case the current directory is present as valid $PATH entry, it is OK
to call the program from it, even if vim curdir is in that same
directory.
(Without that patch, for instance, you will not be able to open .zip
files while your current directory is /bin)

Problem: runtime files may execute code in current dir
Solution: only execute, if not run from current directory
The perl, zig and ruby filetype plugins and the zip and gzip autoload
plugins may try to load malicious executable files from the current
working directory. This is especially a problem on windows, where the
current directory is implicitly in your $PATH and windows may even run a
file with the extension `.bat` because of $PATHEXT.
So make sure that we are not trying to execute a file from the current
directory. If this would be the case, error out (for the zip and gzip)
plugins or silently do not run those commands (for the ftplugins).
This assumes, that only the current working directory is bad. For all
other directories, it is assumed that those directories were
intentionally set to the $PATH by the user.
