fix: correct polyfill paths in nuspec, remove dead code

Lock.cs and DiagnosticClasses.cs were packed to shared/Polyfills/ but
LegacySupport.targets references shared/MSBuild/Polyfills/. Align nuspec
targets across all three SDK variants. Remove obsolete TrimAttributes.cs,
Compiler.cs, and eng/ directory.
