[stubs] Introduce a proper ToBooleanStub.

Rename the existing (patching) ToBooleanStub to ToBooleanICStub to match
our naming convention, and add a new TurboFan-powered ToBooleanStub,
which just does the ToBoolean conversion without any runtime call or
code patching, so we can use it for Ignition (and TurboFan).

Drive-by-fix: Add an Oddball::to_boolean field similar to the ones we
already have for to_string and to_number, so we don't need to actually
dispatch on the concrete Oddball at all.
