bitbake: codeparser: support shell substitutions in quotes

The current shell substitution mechanism only works without quotes. For
example:

  var1=$(cmd1 ...)

Will work and add `cmd1` to the correspondind `run.do_*` file.

However, although quite common, this syntax is not supported:

  var1="$(cmd1 ...)"

This commit adds this feature by adding a step to process_words() to
check whether we are dealing with quotes first, and by iterating on
what's between them to detect new shell substitution candidates. These
candidates are tested and parsed like before in the next step. The
original `part` being part of the candidates means the syntax
var1=$(cmd1 ...) is still valid.
