feat(@schematics/angular): default Ivy apps to AOT true

Testing on AIO with Angular master as of 28/05/2019 I got these results:
JIT ~414ms (369, 378, 408, 323, 593)
AOT using VE ~1383ms (1365, 1185, 1767, 1135, 1467)
AOT using Ivy ~517ms (600, 391, 444, 756, 394)

This is largely due to angular/angular#29380 and angular/angular#30238.

The second PR above was not merged to master, and thus will not be in 8.0.0. This PR should be merged to match it.
