dap: use larger string type variable load limits in 'repl', 'variables' context (#2418)
* dap: use larger variable load limits in 'repl', 'variables' context

When evaluate requests are triggered in the context of 'repl'
(DEBUG CONSOLE in VSCode) or 'variables' (copy values from VARIABLES
section in VSCode), they are the result of human action and have
more rooms to display. So it is not too bad to apply longer limits.

Variable auto-loading for strings or arrays is nice but currently
it's unclear to me how this should be integrated in the DEBUG
CONSOLE or with the Copy Value feature. Until we have better ideas
and tools, let's go with these larger limits.

Unfortunately, the "Copy Value" from WATCH section triggers evaluate
requests with "watch" context and we don't want to load large data
automatically for "watch". So, users who want to query a large value
should first copy the expression to DEBUG CONSOLE and evaluate it.
Not ideal but not the end of the world either.

Updates golang/vscode-go#1318

* dap: apply large limit only to the string type result

* dap: move string reload logic to convertVariable* where other reload logic is

Currently we are thinking string reload for evaluation as a temporary
workaround until we figure out an intutitive way to present long strings.
So, I hope moving this logic near other reload logic may be better.

And, use the address based expression when reloading - when handling the
function return values, we may not have an expression to use.

* dap: make deep source check happy

* dap: move string reevaluation logic back to onEvaluateRequest

Reloading string variables is tricky if they are in registers.
We don't attempt to reload them but for clarity, move this up
to the onEvaluateRequest handler.

For function call, use a generous limit for string load
since the results are volatile.

* dap: check variable isn't affected by evaluate in other context
