Provide an (initially experimental) implementation of the WHATWG Encoding
Standard API (`TextDecoder` and `TextEncoder`). The is the same API
implemented on the browser side.
By default, with small-icu, only the UTF-8, UTF-16le and UTF-16be decoders
are supported. With full-icu enabled, every encoding other than iso-8859-16
is supported.
This provides a basic test, but does not include the full web platform
tests. Note: many of the web platform tests for this would fail by default
because we ship with small-icu by default.
A process warning will be emitted on first use to indicate that the
API is still experimental. No runtime flag is required to use the
feature.

Method format refactored to make it more maintenable, replacing the
switch by a function factory, that returns the appropiated function
given the character (d, i , f, j, s).
Also, performance when formatting an string that contains several
consecutive % symbols is improved. The test:
`const numSamples = 10000000;
const strPercents = '%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%s%%%%%%%%%%%%%%%%%i%%%%%%%%%%%%%%%%%%%%%%%%%%';
var s;
console.time('Percents');
for (let i = 0; i < numSamples; i++) {
s = util.format(strPercents, 'test', 12);
}
console.timeEnd('Percents');`
Original time: 28399.708ms
After refactor: 23763.788ms
Improved: 16%

If a custom inspection function returned `this`, use that value
for further formatting instead of going into infinite recursion.
This is particularly useful when combined with `util.inspect.custom`
because returning `this` from such a method makes it easy to

actually having to provide an alternative for custom inspection.
