[erl_interface] Add ei_x_format* to support all the Erlang syntax

[fregate]

Is your feature request related to a problem? Please describe.
Looks like there is lack of support for basic syntax in ei_x_format* function.
I've found that no support for bitstring/binary syntax (<<>>), numbers in different bases (16#A, 2#101011, 1_3#13_3, 2.3e-3_3).

Describe the solution you'd like
Add support for basic term syntax in this function (bitstring/binary, numbers).

In #7598 been added support for map term, so my suggestion to not stop at this and continue.

Sure. But before adding new features, I think a commit robustifying the existing parsing of lists and tuples, driven by more extended tests like we did for maps in #7602, would be good.
