Bump version to 0.7.3 (#303)

The existing DefaultTargetFramework mechanism already produces
net10.0 pointer packages (OfficialBuild) and net11.0 AOT packages
(OfficialAotBuild). Multi-TFM doesn't work here because library
ProjectReferences all use DefaultTargetFramework, and global
-p:TargetFrameworks leaks to them.
