Shell: Add support for the '!' POSIX pipeline prefix
...
This prefix simply inverts the exit code of the pipeline, which we
implement using the 'not' builtin.

Shell: Handle (most) errors in the parsers
...
This turns all errors into either "OOM" or a proper shell error (if
propagation is impossible or meaningless).
Fixes `echo -en '\xfe\x4a' | $SHELL` crashing.

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.

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.

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>>.

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.
