usb: device_next: msc: handle MODE SENSE(10) command

USB Mass Storage Specification for Bootability requires MODE SENSE(10)
command. MODE SENSE(6) and MODE SENSE(10) generally access the same data
but differ in the maximum allocated length and LLBAA support. However
there is no point in extracting common handling because there no mode
pages are supported now.

Fail MODE SENSE requests if asking for anything other than supported
page codes (to which the essentially hardcoded response is valid).
