Adam Barth 63e7a0e80a Add BuildContext.size as a convenience getter (#6355)
Developers need to get the size of the BuildContext sufficiently often
that we should provide a convenient getter for the value. Having this
getter is also an opportunity to catch common mistakes and provide
useful error messages that guide developers towards better patterns.

Fixes #2321
