  [Dexter] Add ability to rewrite scripts to fill-in unknown values (#202799)

This patch adds a feature to Dexter that allows scripts to be passed to
Dexter with missing expected values (`null` values in YAML), which
Dexter will attempt to "fill-in" with expected values that match the
debugger's actual output. The result is written to a file with the same
name as the original test file, in the directory given by
--results-directory if one is present; all content outside of the Dexter
script itself is preserved exactly as-is.

NB: Each test in this patch has a corresponding "expected" file, which
is almost identical (including the `RUN` lines), and exists to be
`diff`'d against the output of Dexter's script generation.
