Align the inspect output with the one used in the Chrome dev tools.
A recent survey outlined that most users prefer to see the number
of set and map entries. This should count as well for array sizes.
The size is only added to regular arrays in case the constructor is
not the default constructor.
Typed arrays always indicate their size.

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • tests and/or benchmarks are included
  • documentation is changed or added
  • commit message follows commit guidelines

A few tests fail because it affects error messages (in a good way IMO).

@targos thanks, fixed. I got used to not running the full test suite but just use python tools/test.py -j4 test/*/*subsystem* :D

Might be worth a CITGM out of caution. I could see this kind of output change breaking a test somewhere unexpected.

CITGM is "green" (as in: no failures besides flakes)
