Provide bit-casted slot values from DebugTracePlayer.

Previously, the VariableData returned from a DebugTracePlayer contained
values in an int32_t, regardless of the slot's NumberKind. We had a
helper function which could stringize the bits, but otherwise the caller
was responsible for bit-casting the value manually.

Now, the DebugTracePlayer will automatically manage bit-casting for the
caller. The value returned in the VariableData is now a double (so it
is able to store an int32, uint32, or float at full precision).

This change was inspired by the recent Typescript port. (The value in
the Typescript VariableData uses a compound `number | boolean` type, so
it is able to fully represent any slot value natively.)
