This change adds support for computing SHA-256 hashes in the stack
output of errors by adding a function to the prototype of the
`CallSite` object, passed to `Error.prepareStackTrace`. Additionally,
it updates the `hash` property from `Debugger.scriptParsed` and
`Debugger.scriptFailedToParse` to be SHA-256 instead of the
proprietary hash it is today.
It is intended to be an advancement in indexing source maps to
support improved tooling, especially for post-hoc or in-production
diagnostics scenarios.

Doc: https://bit.ly/revive-restart-frame
Context: https://crrev.com/c/3582395 (whole feature)
This CL adds a new optional flag `canBeRestarted` to every call frame
in Debugger.paused events. As the name suggests, the flag indicates
whether we can restart a particular frame through Debugger.restartFrame
once implemented.
We are not able to safely restart all frames:
* We don't support WASM frames
* We don't support frames where resumable functions (async fns,
generators) and embedder C++ frames are between the top-most
frame and the to-be-restarted frame.
Note that from a CDP perspective the flag doesn't actually guarantee
a successful restart. CDP clients can issue
CDP commands between the Debugger.paused event and before a user
decides to restart a frame, which can potentially mess
with the stack.
The `canBeRestarted` flag tests are folded into the
Debugger.restartFrame tests. As the feature is not yet fully
implemented we short-circuit most of the tests for now and only
run them up until the first Debugger.restartFrame call fails
(except "fails-for-resumables.js").
This means the tests exercise the `canBeRestarted` flag, but not
the restarting functionality itself.

Currently, only a scriptURL is reported, which can be over-written by
sourceURL comments of the script. This means a script can basically
claim to come from anywhere. This means that DevTools doesn't know the
resource name the embedder provided if there is a sourceURL comment.
This CL adds a `embedderName` field to the scriptParsed and
scriptFailedToParse events that reports the name the embedder
associated with the script.

The debugger script implementation had its own way to write
uint32_t values to a string as hex values. This removes the
custom code and uses a shared implementation in String16Builder
instead.
The observable effect is that script hashes are now lower-case
and the character sequence is reversed for each 8-character
pair.
