Implement a special async_hooks listener that forwards information
about async tasks to V8Inspector asyncTask* API, thus enabling
DevTools feature "async stack traces".
The feature is enabled only on 64bit platforms due to a technical
limitation of V8 Inspector: inspector uses a pointer as a task id,
while async_hooks use 64bit numbers as ids.
To avoid performance penalty of async_hooks when not debugging,
the new listener is enabled only when the process enters a debug mode:
- When the process is started with `--inspect` or `--inspect-brk`,
the listener is enabled immediately and async stack traces
lead all the way to the first tick of the event loop.
- When the debug mode is enabled via SIGUSR1 or `_debugProcess()`,
the listener is enabled together with the debugger. As a result,
only async operations started after the signal was received
will be correctly observed and reported to V8 Inspector. For example,
a `setInterval()` called in the first tick of the event will not be
shown in the async stack trace when the callback is invoked. This
behaviour is consistent with Chrome DevTools.
Last but not least, this commit fixes handling of InspectorAgent's
internal property `enabled_` to ensure it's set back to `false`
after the debugger is deactivated (typically via `process._debugEnd()`).

Raising SIGABRT is handled in the CRT in windows, calling _exit()
with ambiguous code "3" by default.
This adjustment to the abort behavior gives a more sane exit code
on abort, by calling _exit directly with code 134.

Adds a new `../common/fixtures' module to begin normalizing
`test/fixtures` use. Our test code is a bit inconsistent with
regards to use of the fixtures directory. Some code uses
`path.join()`, some code uses string concats, some other
code uses template strings, etc. In mnay cases, significant
duplication of code is seen when accessing fixture files, etc.
This updates many (but by no means all) of the tests in the
test suite to use the new consistent API. There are still
many more to update, which would make an excelent Code-n-Learn
exercise.

This change removes `common.noop` from the Node.js internal testing
common module.
Over the last few weeks, I've grown to dislike the `common.noop`
abstraction.
First, new (and experienced) contributors are unaware of it and so it
results in a large number of low-value nits on PRs. It also increases
the number of things newcomers and infrequent contributors have to be
aware of to be effective on the project.
Second, it is confusing. Is it a singleton/property or a getter? Which
should be expected? This can lead to subtle and hard-to-find bugs. (To
my knowledge, none have landed on master. But I also think it's only a
matter of time.)
Third, the abstraction is low-value in my opinion. What does it really
get us? A case could me made that it is without value at all.
Lastly, and this is minor, but the abstraction is wordier than not using
the abstraction. `common.noop` doesn't save anything over `() => {}`.
So, I propose removing it.

* Remove needless RegExp flag
In fixed case, `/g` flag is needless in the boolean context.
* Remove needless RegExp capturing
Use non-capturing grouping or remove capturing completely when:
* capturing is useless per se, e.g. in test() check;
* captured groups are not used afterward at all;
* some of the later captured groups are not used afterward.
* Use test, not match/exec in boolean context
match() and exec() return a complicated object,
unneeded in a boolean context.
* Do not needlessly repeat RegExp creation
This commit takes RegExp creation out of cycles and other repetitions.
As long as the RegExp does not use /g flag and match indices,
we are safe here.
In tests, this fix hardly gives a significant performance gain,
but it increases clarity and maintainability,
reassuring some RegExps to be identical.
RegExp in functions are not taken out of their functions:
while these functions are called many times
and their RegExps are recreated with each call,
the performance gain in test cases
does not seem to be worth decreasing function self-dependency.

This is first in a hoped-for series of moves away from a monolithic
common.js that is loaded for every test and towards a more modular
approach. (In the end, common.js will hopefully contain checks for
variables leaking into the global space and perhaps some of the more
ubiquitous functions like common.mustCall().)
Move the WPT testing code to its own module.
