Added gRPC functions to manage libraries in profiles (#3019)

* Added gRPC functions to manage libraries in profiles

* Removed ProfileDump gRPC command.

As stated by @per1234:

> Build profile data is already provided via the LoadSketch method, so it
> seems that even a mechanism that is truly for getting profile data should
> be implemented by simply expanding the SketchProfile message to contain
> all the data of the build profile (actually kind of silly that it
> currently only provides a subset of the profile data).

#3019 (comment)

* Moved SketchProfileLibraryReference in the proper commono.proto file

* linter: removed unneeded type specification

* Renamed SketchProfileLibraryReference -> ProfileLibraryReference

* Renamed InitProfile -> ProfileCreate

And also corresponding messages:

  InitProfileRequest -> ProfileCreateRequest
  InitProfileResponse -> ProfileCreateResponse

* Small refactoring, no code change

* Fixed error messages

* Removed unnecessary type specifier

* Refactored libraryResolveDependencies.

The function is now split into two functions:

- librariesGetAllInstalled that requires a librariesmanager.Explorer.
- libraryResolveDependencies that requires only a librariesindex.Index
  and do not require anymore a librariesmanager.Explorer.

* Added support for 'dependency:' field in profiles libraries

* ProfileLibAdd and ProfileLibRemove can now cleanup unneeded dependencies

* Better error messages

* Simplified Profile.RemoveLibrary(...) method.

* Fixed algorithm for determination of required deps

* Updated docs

* Rename DuplicateProfileError -> ProfileAlreadyExitsError

* Removed useless field in gRPC ProfileCreateResponse

* fix: ProfileCreate sets the new profile as default only if asked to do so

* Improved docs

* Applied code review suggestion

* Using cmp.Or helper
