Problem: The "*.*" browsefilter pattern only matches all files on
Windows (Daryl Lee)
Solution: Use "*" to filter on all platforms but keep "*.*" as the label
text on Windows. (Fixes#12685, Doug Kearns)
The *.* browsefilter pattern used to match "All Files" on Windows is a
legacy of the DOS 8.3 filename wildcard matching algorithm. For reasons
of backward compatibility this still works on Windows to match all
files, even those without an extension.
However, this pattern only matches filenames containing a dot on other
platforms. This often makes files without an extension difficult to
access from the file dialog, e.g., "Makefile"
On Windows it is still standard practice to use "*.*" for the filter
label so ftplugins should use "All Files (*.*)" on Windows and "All
Files (*)" on other platforms. This matches Vim's default browsefilter
values.
This commit also normalises the browsefilter conditional test to check
for the Win32 and GTK GUI features and an unset b:browsefilter.

This is a followup to 816fbcc262 (patch
9.0.1833: [security] runtime file fixes)
It basically disables that external commands are run on loading of the
filetype plugin, **unless** the user has set the `g:plugin_exec = 1`
global variable in their configuration or for a specific filetype the
variable g:<filetype>_exec=1.
There are a few more plugins, that may execute system commands like
debchangelog, gitcommit, sh, racket, zsh, ps1 but those do at least
do not run those commands by default during loading of the filetype plugin
(there the command is mostly run as convenience for auto-completion or
to provide documentation lookup).

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)

While making changes to the ruby ftplugin, slightly change the exepath()
conditional from patch 9.0.1833 and move it after the :cd invocation.

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.
