Debug: provide an option to _not_ call die()

[sabina-talipova]

Description

• Add support for user defined config: Debug::die_on_notice(bool).

The Debug::endshow() method calls die() at the end. Various other methods such as dump() do not.
We should provide a way for the developer to decide whether they want to call die() or not, perhaps via a new static such as dieOnNotice() which accepts a bool, and the bool determines if the methods should call die() or not.

See:

silverstripe-framework/src/Dev/Debug.php

Lines 29 to 30 in cf78a9d

	* @todo add support for user defined config: Debug::die_on_notice(true | false)
	* @todo better way of figuring out the error context to display in highlighted source

@sabina-talipova Do you know what is intended by either of those todo notes? I'm not sure what is intended and wouldn't know how to implement this.
If you have more context please add it - otherwise this might be one we should close.

I've updated ticket. I'm not quite sure, should we provide some sort of functionality to user. It's just how I understood this todo comment.
If you think it's not necessary we can close this issue.
