Add mountpoint for macos

[TimeEngineer]

closes #6144

This is a start on the implementation of mountpoint for MacOS, it should be possible to use fuser for macOS, it uses macfuse(osxfuse is the old name).
fuser clearly shows that it supports macOS but it is untested (because you can find #[cfg(target_os = "macos")] in its code and see: https://github.com/cberner/fuser?tab=readme-ov-file#macos-untested where it describes how to install macfuse)

What I have done in this PR:

• Shorcut the CI to test macOS platform only
• Printed where the problem comes from (It's when we call Session::new)
• When I installed macfuse, pkg-config --list-all returns fuse in its list, so the reason is not that fuser can't find the library: you can see in build.rs: https://github.com/cberner/fuser/blob/master/build.rs#L11 it searches for fuse (it could be fuse4x according to https://github.com/fusepy/fusepy/blob/master/fuse.py#L90-L91 which is missing in the build.rs)
• According to an issue on fuser, the problem comes from an infinite loop when you mount: Bug on Mac OS cberner/fuser#211 this is also how it appears on the CI: the test timeout
• I have tried to tweak fuser's version, because fuse-rs which was the old repository of fuser seemed to maintain MacOS (see: https://github.com/zargony/fuse-rs?tab=readme-ov-file#macos) I have also found a crate which use an old version (which is not compatible with our version of fuser for linux): https://github.com/mgree/ffs/blob/main/Cargo.toml#L30
• I tried to debug on the CI, but it seems too hard to find how the bug comes from, so I asked to debug on MacOS device.

Remote machine: (with sw_vers)
ProductName: macOS
ProductVersion: 14.4.1
BuildVersion: 23E224

• Note that the CI uses macos-12

• I installed macfuse with brew install --cask macfuse

• When I run the example hello.rs of fuser, it throws the following error message: mount_macfuse: the file system is not available (1) with: fuse_mount_compat25

• I tried /usr/bin/sudo /usr/bin/kmutil load -p /Library/Filesystems/macfuse.fs/Contents/Extensions/14/macfuse.kext on the remote machine which throw Error Domain=KMErrorDomain Code=27 "Extension with identifiers io.macfuse.filesystems.macfuse not approved to load. Please approve using System Preferences." UserInfo={NSLocalizedDescription=Extension with identifiers io.macfuse.filesystems.macfuse not approved to load. Please approve using System Preferences.}

• I found Macfuse 4.6.0 not working macOS Sonoma 14.3.1 osxfuse/osxfuse#1000 which is a similar issue, but I don't know how to access gui interface from terminal :(
