Improve vm trace output

[raskad]

The vm trace output currently has a few issues.

Functions without a name should be identifiable. Currently a function without a name will have printed trace output like this:

----------------- Compiled Output '' ------------------

@jasonwilliams proposed to have some kind of ID for functions that can make them identifiable between the trace of the compiled output and the call frame execution trace. For the proposed output look at this comment: https://github.com/boa-dev/boa/pull/1697#discussion_r741810958

Call Frame outputs are combined when a Call Frame returns

When a Call Frame (function/constructor) returns it is not visible, where one Call Frame ends and where the other one continues:

...
----------------------------------------- Call Frame -----------------------------------------
Time          Opcode                     Operands                   Top Of Stack

1μs           PushLiteral                0                          "hello"
3μs           Return                                                "hello"
134μs         GetPropertyByName          0004: 'test'               "hello"
...

In this example, the called function ends after the Return opcode. The GetPropertyByName opcode belongs to the caller function that is now running again. This should be clearly visible in the trace output.

Another example. For this JS code:

const a = { b: 5 };
a['b']++;
a.b;

You get something like this. It seems that if the opcode names are too long, the operands jump to a new line:

----------------------Compiled Output: '<main>'-----------------------
    Location  Count   Opcode                     Operands
