debug: display byte/uint8/rune slices as strings for readability

See the original discussion on microsoft/vscode-go#1385.

any works on this issuse? it is very useful for bytes debug, otherwise i must do

s := string(r)
_ = s

where nedded and rerun debuger. 😖

Our expression evaluation follows dlv's expression syntax. (https://github.com/go-delve/delve/blob/master/Documentation/cli/expr.md) which already supports type casts between string, []byte, and []rune.

So, users can enter string(s) in the Debug Console or register it

in the watch panel.

Not all byte slices make sense as strings. So, I think letting users selectively select the slices of interest and explicitly perform type casting on those is reasonable. Closing.

But Goland handles this

@emil14 Not all of us use goland. Screenshot and video that handles non-printable bytes may be helpful.

@hyangah

In goland you have this "View" button, after click on it you see a string

@emil14 This issue has been revisited at #1459 if you have additional input. Thank you.
