inspector_ui: Split out size from bounds string (#39703)

# How

Tweak the way in which inspected element bounds and size are printed to
improved readability of GPUI Inspector data.

> [!note]
> It looks like the only place in the workspace where bounds are used
within formatted print is GPUI Inspector panel, but I decided to do not
alter [GPUI `geometry.rs` default
format](https://github.com/zed-industries/zed/blob/a7e7f460205bc6eaa397f20c1bcf8c4105d93403/crates/gpui/src/geometry.rs#L1579-L1587),
since adding multiline output and additional labels in there does not
feel like the beast approach, but maybe I'm wrong?

Release Notes:

- N/A
