Commit c57b3367be (worktree: teach `list` to annotate locked worktree,
2020-10-11) taught "git worktree list" to annotate locked worktrees by
appending "locked" text to its output, however, this is not listed in
the --porcelain format.
Teach "list --porcelain" to do the same and add a "locked" attribute
followed by its reason, thus making both default and porcelain format
consistent. If the locked reason is not available then only "locked"
is shown.
The output of the "git worktree list --porcelain" becomes like so:
$ git worktree list --porcelain
...
worktree /path/to/locked
HEAD 123abcdea123abcd123acbd123acbda123abcd12
detached
locked
worktree /path/to/locked-with-reason
HEAD abc123abc123abc123abc123abc123abc123abc1
detached
locked reason why it is locked
...
In porcelain mode, if the lock reason contains special characters
such as newlines, they are escaped with backslashes and the entire
reason is enclosed in double quotes. For example:
$ git worktree list --porcelain
...
locked "worktree's path mounted in\nremovable device"
...
Furthermore, let's update the documentation to state that some
attributes in the porcelain format might be listed alone or together
with its value depending whether the value is available or not. Thus
documenting the case of the new "locked" attribute.

The porcelain format has a line per attribute. Attributes are listed with a
label and value separated by a single space. Boolean attributes (like `bare`
and `detached`) are listed as a label only, and are present only
-if the value is true. The first attribute of a working tree is always
-`worktree`, an empty line indicates the end of the record. For example:
