Ruben Bridgewater 0518b9edf3 assert: multiple improvements
1) Switched + / - and red / green in diffs. It seems like that style
   is more natural to most people.

2) Short primitives do not use the diff anymore. Especially short
   numbers can be read well like 1 !== 2. Cases that can not be
   displayed like that (e.g., -0 and +0) use the regular diff output.

3) Improved error descriptions. It was not always clear what the
   messages stood for. That should now be resolved.

4) Added a position indicator for single lines in case a tty is used
   and the line is shorter than the visual columns.

5) Color detection is now done by checking stderr instead of stdout.

Ruben Bridgewater 560925fe22 assert: make sure throws is able to handle primitives
This fixes some possible issues with `assert.throws` and
`assert.rejects` in combination with an validation object. It will
now properly handle primitive values being thrown as error.

It also makes sure the `generatedMessage` property is properly set
if `assert.throws` or `assert.rejects` is used in combination with
an validation object and improves the error performance in such cases
by only creating the error once.

In addition it will fix detecting regular expressions from a different
context such as n-api that are passed through as validator for
`assert.throws` or `assert.rejects`. Until now those were not tested.

Ruben Bridgewater bfe54df812 assert: improve default error messages
This improves the error messages for:
- assert.notDeepStrictEqual
- assert.deepStrictEqual
- assert.notStrictEqual
- assert.strictEqual

Those will now always use the same error message as used in the
strict mode.

Ruben Bridgewater a1c96f8e07 assert: improve assert.throws
This switches the assert.throws output to the one used in strict mode
if a error object is used for comparison. From now on it will show
the complete difference between two objects instead of only showing
the first failing property.

It also fixes detecting properties with a undefined value and fails
in case the thrown error does not contain the value at all.

Ruben Bridgewater cccddc59e5 assert: fix throws trace
The current stack trace thrown in case `assert.throws(fn, object)`
is used did not filter the stack trace. This fixes it.
