Work around unintended modification time updates on Apple Silicon Macs running macOS 12 and later

When mapping I/O buffers to memory in the kernel extension, the desired memory protection level needs to be specified on Apple Silicon Macs. Mapping the buffer with the default protection level results in unnecessary writes and unintended modification time updates in the future. However, there is no public API for specifying the desired memory protection level on macOS 11.

As a result of this change, macFUSE ships with dedicated kernel extensions for macOS 12 and macOS 14 in addition to the macOS 11 kernel extension.
