Convert SHA256_LENGTH from a constant-in-anonymous-enum to a static const. This defines the constant where it's declared to preserve the existing readability.

Normally this makes things like DCHECK_EQ() unhappy, but when I'd originally tested this I didn't seem to need to make any changes due to that.  Will be watching the trybots...

The original motiviation for this change was to find a way to eliminate some cases of passing anonymous-typed values as template arguments (which happens when you use a value from the enum in e.g. EXPECT_EQ()), which is technically illegal in C++03, though we don't warn about it. Simply naming the enum would have done this, but in general naming enums used to declare constants like this is bizarre ("enum Constants { ... }"?).
