[swift] Parent hierarchy and properties improvements

[prabhu]

With this PR, we use the name from Package.swift for local modules instead of the directory names.

Tested with this multi-module repo that exhibited the issue: https://github.com/elmetal/multi-module-testing-swift

Example: MyPackage is used here instead of MyLib (directory name).

https://github.com/elmetal/multi-module-testing-swift/blob/fe9d96e7a04ed390101e7b92cebc26cfe15f1141/Sources/MyLib/Package.swift#L7

BOM includes 3 components and 3 dependencies

There is also an open question regarding the name value for all swift packages.
