When gjs overhauled its coding style, it opted for disallowing
spaces around braces in object literals: `{foo: 42}`.
We opted out of that particular rule in commit 09b8e8f, primarily
because it would have been a very intrusive change with the old
style of object literals:
```js
let oldStyle = { foo: 42,
bar: 23 };
```
Alas, all multi-line object literals have been transitioned to
the new style where braces go on separate lines, so they are no
longer subject to the rule one way or the other.
Nowadays the rule mostly affects destructuring, and there it
is a bit odd to apply different spacing rules to arrays and
objects:
```js
const [foo, bar] = someArray;
const { baz, quz } = someObject;
```
This is now the main divergence from the canonical gnome style,
and the only one where we directly contradict it.
It would be good to transition away from that, and as the rule
now only affect destructuring and single-line object literals,
we can do that on a case-by-case bases by moving the override
to the legacy configuration.
As desctructuring imports makes up a fair share of the affected
code, and those will change when moving to ES6 modules, this
seems like a good moment to start that transition.

We have made good progress on object literals as well, although there
are still a lot that use the old style, given how ubiquitous object
literals are.
But the needed reindentation isn't overly intrusive, as changes are
limited to the object literals themselves (i.e. they don't affect
surrounding code).
And given that object literals account for quite a bit of the remaining
differences between regular and legacy rules, doing the transition now
is still worthwhile.

It's unfortunate that we cannot fully embrace template strings, but
we aren't limited to "legacy" formatting either; replace the last
remaining places where we still use string concatenation to reduce
the difference between regular and legacy style a bit.

In addition to the changes in this commit, gjs now
restricts the use of the Format module and initFormat.
We can't really replace those for translatable strings
until xgettext gains support for template strings, so
leave that bit out for now.
The other notable change is that gjs now requires
jsdoc comments. We can't plainly enable those options
without a massive amount of work first, but let's see
how requiring doc comments for new code goes.
