LibJS: Fix Object.prototype.valueOf() behavior
...
No idea why it was implemented like this, but a value_of() call on the
coerced object is not part of the spec. Also added some tests.

This is currently a TC39 Stage 2 proposal, but let's go for it!

I wrote the C++, @linusg found bugs and wrote the test.

LibJS: Make Object.getOwnPropertyDescriptor() work with string indexed property
...
E.g. for "0" we have to contruct a PropertyName with Type::Number so it
looks in the indexed properties as expected.

LibJS: Fix Object.getOwnPropertyDescriptor() attributes for numeric property
...
We were getting the attributes of the existing value and then
immediately assigned the default attributes instead.

LibJS: Fix crash in Object.{freeze,seal}() with indexed properties
...
This was failing to take two things into account:
- When constructing a PropertyName from a value, it won't automatically
convert to Type::Number for something like string "0", even though
that's how things work internally, since indexed properties are stored
separately. This will be improved in a future patch, it's a footgun
and should happen automatically.
- Those can't be looked up on the shape, we have to go through the
indexed properties instead.
Additionally it now operates on the shape or indexed properties directly
as define_property() was overly strict and would throw if a property was
already non-configurable.
Fixes #6469 .
