Teach Git to detect remote working directories on MacOS and mark them as
incompatible with FSMonitor.
With this, `git fsmonitor--daemon run` will error out with a message
like it does for bare repos.
Client commands, like `git status`, will not attempt to start the daemon.

Extend generic incompatibility checkout with platform-specific
mechanism. Stub in Win32 version.
In the existing fsmonitor-settings code we have a way to mark
types of repos as incompatible with fsmonitor (whether via the
hook and ipc APIs). For example, we do this for bare repos,
since there are no files to watch.
Extend this exclusion mechanism for platfor-specific reasons.
This commit just creates the framework and adds a stub for Win32.

Bare repos do not have a working directory, so there is no
directory for the daemon to register a watch upon. And therefore
there are no files within the directory for it to actually watch.

Move FSMonitor config settings to a new `struct fsmonitor_settings`
structure. Add a lazily-loaded pointer to `struct repo_settings`.
Create `fsm_settings__get_*()` getters to lazily look up fsmonitor-
related config settings.
Get rid of the `core_fsmonitor` global variable, and add support for
the new `core.useBuiltinFSMonitor` config setting. Move config code
to lookup the existing `core.fsmonitor` value to `fsmonitor-settings.[ch]`.
The `core_fsmonitor` global variable was used to store the pathname to
the FSMonitor hook and it was used as a boolean to see if FSMonitor
was enabled. This dual usage will lead to confusion when we add
support for a builtin FSMonitor based on IPC, since the builtin
FSMonitor doesn't need the hook pathname.
Replace the boolean usage with an `enum fsmonitor_mode` to represent
the state of FSMonitor. And only set the pathname when in HOOK mode.
