Sam Brannen 0127de5a7a Enforce read-only semantics in SpEL's SimpleEvaluationContext

SimpleEvaluationContext.forReadOnlyDataBinding() documents that it
creates a SimpleEvaluationContext for read-only access to public
properties; however, prior to this commit write access was not disabled
for indexed structures when using the assignment operator, the
increment operator, or the decrement operator.

In order to better align with the documented contract for
forReadOnlyDataBinding(), this commit makes it possible to disable
assignment in general in order to enforce read-only semantics for
SpEL's SimpleEvaluationContext when created via the
forReadOnlyDataBinding() factory method. Specifically:

- This commit introduces a new isAssignmentEnabled() "default" method
  in the EvaluationContext API, which returns true by default.

- SimpleEvaluationContext overrides isAssignmentEnabled(), returning
  false if the context was created via the forReadOnlyDataBinding()
  factory method.

- The Assign, OpDec, and OpInc AST nodes -- representing the assignment
  (=), increment (++), and decrement (--) operators, respectively --
  now throw a SpelEvaluationException if assignment is disabled for the
  current EvaluationContext.
