Matthew Dempsky 1a8b4e05b1 cmd/compile: unique LinkString for renamed, embedded fields ...

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.
