Improve Console Implementation

[Redfire75369]

The console implementation is currently quite bare bones, and does not follow the specification.

The specification specifies log levels for each of the functions on console. These levels should be honoured except for console.debug which will have LogLevel::Debug.

In addition, a formatter should be implemented to format strings according to the %s, %d, %i, %f, %o, %O specifiers. Do note that %% stands for % in the final string. All arguments passed to the various logging functions that take variable arguments (varargs) should pass them to the formatter function to obtain the string. If possible, the %c specifier can also be implemented, but extra work will be required.

The formatter should also be exposed from js, either as console.format or in some other form.

Requirements: Basic in JavaScript, Basic in Rust
Difficulty: Basic

[Redfire75369]

As of 6425540, format specifiers %{s,d,i,f,o,O} are implemented, and %c is ignored. Log levels have also been updated.

The remaining issue is exposing the formatter to JS.
