Using type aliases, it's possible to create structs with embedded
fields that have no corresponding type literal notation. However, we
still need to generate a unique name for these types to use for linker
symbols. This CL introduces a new "struct{ Name = Type }" syntax for
use in LinkString formatting to represent these types.
Reattempt at CL 372914, which was rolled back due to race-y
LocalPkg.Lookup call that isn't safe for concurrency.
Fixes #50190.
