helper/schema: Computed -> NewValueKnown, add comments to GetOkExists
Added some more context to GetOkExists, moved Computed to NewValueKnown
to accommodate some changes that will be coming up in HCL2 that may make
"Computed" less intuitive of a function name, and updated the docs for
NewValueKnown as well.

helper/schema: Add Computed to ResourceDiff, expose GetOkExists
This adds a new method to ResourceDiff: Computed, which exposes the
computed read result field to ResourceDiff. In the context of
customizing the diff, this is important as interpolated and otherwise
computed values will show up in the diff as blank, with no way of
determining if the value is actually blank or if it's a computed value
not available at diff customization time. Currently assumptions need to
be made on this, but this does not help in validation scenarios where
one needs to differentiate between an actual blank value and a value
that will be available later.

This is exposed for the most part via NewComputed in the diff, but the
tests cover both the config reader as well (with no diff, even though
this should not come up in normal operation) and also the newDiff reader
when someone sets a new value using SetNew and SetNewComputed.

This commit also exposes GetOkExists. The tests were mostly pulled from
ResourceData but a few were added to ensure that config was being
properly covered as well, in addition to covering SetNew and
SetNewComputed.

Chris Marchesi 3ac0cdf0c0 helper/schema: Better ResourceDiff schema key validation
This fixes nil pointer issues that could come up if an invalid key was
referenced (ie: not one in the schema). Also ships a helper validation
function to streamline things.

Chris Marchesi 931b0e1441 helper/schema: Remove exported SetDiff method
The consensus is that it's a generally better idea to move setting the
functionality of old values completely to the refresh/read process,
hence it's moot to have this function around anymore. This also means we
don't need the old value reader/writer anymore, which simplifies things.

Chris Marchesi 22220fd0f7 helper/schema: Final set of ResourceDiff tests, bug fixes
Final set of coverage for ResourceDiff and bug fixes to correct issues
the test cases brought up.

Will be dropping ClearAll in next commit, as with how this interface is
intended to be used, it does not really make much sense.

Chris Marchesi 64cc4084d2 helper/schema: ResourceDiff tests, bug fixes
The beginning of tests for SetNew. Noticed that removed values are not
logged for computed keys in a diff - not too sure if that is going to be
a problem (possibly not as GetChange in ResourceData should still
reference state for the old value). I came on this most notably in the
"TestSetNew/complex-ish_set_diff" test, for reference.

More tests pending for other functions for coverage of other functions
and test cases as defined in #8769.
