Markus Armbruster 3f7febc937 qom: Improve error messages when property has no getter or setter
When you try to set a property that has no setter, the error message
blames "insufficient permission":

    $ qemu-system-x86_64 -S -display none -nodefaults -monitor stdio
    QEMU 7.1.50 monitor - type 'help' for more information
    (qemu) qom-set /machine type q35
    Error: Insufficient permission to perform this operation

This implies it could work with "sufficient permission".  It can't.
Change the error message to:

    Error: Property 'pc-i440fx-7.2-machine.type' is not writable

Do the same for getting a property that has no getter.
