    tools/test/stress2/misc: Add msdosfs tests for surrogate pairs
    
    Test msdos22.sh creates 1000 files with long random names consisting
    of only ASCII characters. The mount is performed without -L option,
    therefore no use of iconv to convert between character sets.
    
    Test msdos23.sh mixes some non-ASCII characters into the file names.
    The file system is therefore mounted with -L C.UTF-8 to include tests
    of the conversions between UTF-8 and UTF-16.
    
    Test msdos24.sh adds emojis to the names to test the (not yet
    committed) support of UTF-16 surrogate pairs in filenames.
    
    (cherry picked from commit aa029088ec130d71b406c4118346fbd933940826)
    (cherry picked from commit 11f23d7c078b319285727d277f05b6962280bcce)
    (cherry picked from commit 596dadbbb5a711477f811fed65a6c463801d16c5)
