bitbake: codeparser.py: support deeply nested tokens

For shell constructs like
   echo hello & wait $!
the process_tokens() method ended up with a situation where "token"
in the "name, value = token" assignment was a list of tuples
and not the expected tuple, causing the assignment to fail.

There were already two for loops (one in _parse_shell(), one in
process_tokens()) which iterated over token lists. Apparently the
actual nesting can also be deeper.

Now there is just one such loop in process_token_list() which calls
itself recursively when it detects that a list entry is another list.

As a side effect (improvement?!) of the loop removal in
_parse_shell(), the local function definitions in process_tokens() get
executed less often.

Fixes: [YOCTO #10668]
