ShellPkg/ShellCommandLib: Update DumpHex to print {|}~ 

ASCII characters {|}~ should be printed by DumpHex. The problem is that
if you have a string like

    {xizzy}~{foo|bar}~{quux}

in the dumped data, it will not appear as such in the *-delimited ASCII
column to the right, but as

    .xizzy...foo.bar...quux.

which is less than ideal.

Most of the commit message was inspired by/shamelessly stolen from
Laszlo's example:
