Fix sizing and alignment issues with multi-line containers (facebook#…

…1513)

Summary:

X-link: facebook/react-native#41916

Fixes facebook#1300
Fixes facebook#1008

This fixes a smattering of issues related to both sizing and aligment of multi-line-containers:

1. We were previously incorrectly bounding the size of each flex line to the min/max of the entire container.
2. Per-line leads were sometimes incorrectly contributing to alignment within the line
3. The cross dim size used for multi-line alignment is not correct, or correctly clamped. If the available size comes from a max constraint, that was incorrectly used instead of a definite size, or size of content. Leads were entirely skipped for min constraint.

Need to test how breaking this is, to see if it might need to go behind an errata.
