test-util-format checks the message of an error that is
generated by the JavaScript engine. Error messages that change in the
underlying JavaScript engine should not be breaking changes in Node.js
and therefore should not cause tests to fail. Remove the message check
and replace it with a check of the type of the Error object along with
the absence of a `code` property. (If a `code` property were present, it
would indicate that the error was coming from Node.js rather than the
JavaScript engine.)
This also makes this test usable without modification in the ChakraCore
fork of Node.js.

The main optimizations are
- Removed visibleKeys
- Removed proxy cache
- Removed Object.assign
- No key concatenating anymore
- No key recalculating anymore
- Improved indentation logic
- Improved string escape logic
- Added many fast paths
- Optimized code branches a lot
- Optimized (boxed) primitive handling
- Inline code if possible
- Only check extra keys if necessary
- Guard against unnecessary more expensive calls
This also fixes a bug with special array number keys as e.g. "00".
Besides that there were lots of smaller optimizations, the
code got a bit cleaned up and a few more tests got in.

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%

Previously all errors resulting from JSON.stringify were treated as a
proof for circularity of the object structure. That is not the case if
the `toJSON` method of the object throws an error. Explicitly check for
the exact error message when determining the object structure's
cyclicity.

A number of test files use IIFEs to separate distinct tests from
each other in the same file. The project has been moving toward
using block scopes and let/const in favor of IIFEs. This commit
moves IIFE tests to block scopes. Some additional cleanup such
as use of strictEqual() and common.mustCall() is also included.

Previously, Error objects were formatted as the result of a `toString`
call bounded by square brackets. They are now formatted as the stack
trace for the given error object. The intention initially was to emulate
how browsers do `console.error` but since that would also impact
`console.warn`, `console.log`, etc, it was decided to make the change at
`util.inspect` level which is in turn used by the `console` package.

common.js needs to be loaded in all tests so that there is checking
for variable leaks and possibly other things. However, it does not
need to be assigned to a variable if nothing in common.js is referred
to elsewhere in the test.

Enable linting for the test directory. A number of changes was made so
all tests conform the current rules used by lib and src directories. The
only exception for tests is that unreachable (dead) code is allowed.
test-fs-non-number-arguments-throw had to be excluded from the changes
because of a weird issue on Windows CI.
