ArmPlatformPkg/Bds: Introduced helper function to detect if an Ascii/Unicode string is printable
Some limitations:
- it only supports unicode string that use ASCII character (< 0x100)
- single character ASCII strings are interpreted as Unicode string
- string cannot be longer than 2 x BOOT_DEVICE_OPTION_MAX (600 bytes)
