Added CDC functional descriptor structs to the Low Level CDC demos and CDC...

Added CDC functional descriptor structs to the Low Level CDC demos and CDC class bootloader, to improve the readability of the descriptors.

Fixed BootloaderCDC project failing on some operating systems due to removed Line Encoding options (thanks to Alexey Belyaev).
