Cleanup

[Razican]

While doing the rebase of #1272 I found some inconsistencies, so I tried to fix them here:

• Upgraded Rust + JS dependencies
• Improved style of some @@ToStringTag definitions, using Self::NAME when possible
• Updated the Test262 submodule
• Using Value::nan() instead of conversions
• Added build tests for examples

Isn't it strange that the number of passing tests went down?

A comparison using the same commit for Test262 shows that indeed there are 4 new failing tests. I will check what is happening. It seems that updating the Test262 they fixed some tests and this brings up the number of failures somehow.
