Shell: Allow assignment-prefixed commands to run builtins
...
`env` is not capable of running shell builtins, so make a simple
builtin in its place.

Shell: Correctly handle escaped quote characters in strings
...
Previously "foo\`bar" was treated literally, but \` is a valid escape
character.
This commit makes that string correctly evaluate as "foo`bar".

Shell: Correctly handle commands after heredoc contents
...
Previously we did not emit a newline after the ending heredoc key, which
wreaked havoc on the parser logic, leading to parse errors.

Shell: Use the correct range for named variable expansions
...
Previously we were starting the variable expansions before the starting
'$' and calculating the wrong length, this commit makes it so we
calculate the right range for them.

Shell: Allow appending empty string literals

Otherwise, we just silently drop arguments that are empty strings.

Shell: Implement arithmetic expansions for POSIX mode
...
This also adds a 'math' immediate function that can be used in Shell
proper to do arithmetic stuff.

Everywhere: Stop using NonnullRefPtrVector
...
This class had slightly confusing semantics and the added weirdness
doesn't seem worth it just so we can say "." instead of "->" when
iterating over a vector of NNRPs.
This patch replaces NonnullRefPtrVector<T> with Vector<NNRP<T>>.

Everywhere: Use '_{short_,}string' literals more
...
This mostly updates code what was written before but merged after these
were added.

This starts by switching all AST members to Strings, and dealing with

Shell: Start implementing a POSIX-compliant parser
...
The parser is still very much a work-in-progress, but it can currently
parse most of the basic bits, the only *completely* unimplemented things
in the parser are:
- heredocs (io_here)
- alias expansion
- arithmetic expansion
There are a whole suite of bugs, and syntax highlighting is unreliable
at best.
For now, this is not attached anywhere, a future commit will enable it
for /bin/sh or a `Shell --posix` invocation.
