host msc: call read_capacity as part of enumeration

- add tuh_msc_get_block_count(), tuh_msc_get_block_size()
- rename tuh_msc_mounted_cb/tuh_msc_unmounted_cb to
tuh_msc_mount_cb/tuh_msc_unmount_cb to match device stack naming
- change tuh_msc_is_busy() to tuh_msc_ready()
- add CFG_TUH_MSC_MAXLUN (default to 4) to hold lun capacities
- add host msc configured to for state check.
