db886fe18b Userland+AK: Stop using getopt() for ArgsParser
This commit moves the implementation of getopt into AK, and converts its
API to understand and use StringView instead of char*.
Everything else is caught in the crossfire of making
Option::accept_value() take a StringView instead of a char const*.

With this, we must now pass a Span<StringView> to ArgsParser::parse(),
applications using LibMain are unaffected, but anything not using that
or taking its own argc/argv has to construct a Vector<StringView> for
this method.

1cf45ee930 Utilities: Add ttfdisasm for disassembling OpenType instructions
This utility when given a .tff font provides options for disassembling:

 - The 'fpgm' table, this a program that's run once when the font is
   loaded. It's used to define instructions and functions used by used
   by other programs.

 - The 'prep' table, this is a general program that's run when ever
   the font size (or other properties) changes.

 - And the programs associated with any individual glyph.

The disassembly is printed in a format that matches the examples from:
https://learn.microsoft.com/en-us/typography/opentype/spec/tt_instructions

I'm mainly adding this because I think it's neat to be able to look
at these things, and think it'll be helpful for debugging an
interpreter.

With this you can see that all of the LiberationSerif-XXX.tff fonts in
Serenity have these programs ready to go.
