When generating an assertion error message,
`filename` might be undefined,
e.g. if `assert` is called in `eval`.
Handle this case gracefully instead of failing with
`Cannot read property 'endsWith' of undefined`.

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.

This moves the `assert` parts from `internal/errors` into an own

One of the biggest downsides to the `assert.throws` API is that it
does not check for the error message in case that is used as second
argument. It will instead be used in case no error is thrown.
This improves the situation by checking the actual error message
against the provided one and throws an error in case they are
identical. It is very unlikely that the user wants to use that error
message as information instead of checking against that message.

`lib/internal/bootstrap_loaders.js`, and documents them there.
This file will be compiled and run before `bootstrap_node.js`, which
means we now bootstrap the internal module & binding system before
actually bootstrapping Node.js.
- Rename the special ID that can be used to require `NativeModule`
as `internal/bootstrap_loaders` since it is setup there. Also put
`internalBinding` in the object exported by `NativeModule.require`
instead of putting it inside the `NativeModule.wrapper`
- Use the original `getBinding()` to get the source code of native
modules instead of getting it from `process.binding('native')`
so that users cannot fake native modules by modifying the binding
object.
