Building on #3214 and #3215, updates sem_ir yaml to be: ``` - filename: name sem_ir: [ ... ] ``` Also, changes the textual format from `package { ... }` to `file <filename> { ... }`. My thought on packages there is: ``` file "foo.carbon" { package MyPackage ... } ``` The reason for putting the file first is that it's easier if we put what we're grouping on first, whereas the package is an "annotation" on the file.
