[language-runtime] Implement GetRequiredPackages to replace GetRequiredPlugins

[Zaid-Ajaj]

Description

The .NET language runtime currently uses GetRequiredPlugins to determine which resource plugins a program needs in order to run. However, GetRequiredPlugins doesn't account for the parameterization of the plugins. This is where GetRequiredPackages comes into play which allows the language runtime to return required plugins/packages along with their parameterization info (loaded from pulumi-plugin.json files).

This also allows the language runtime to correctly work with pulumi import for parameterized providers.

Fixes #432 and unskips tests:

• l2-parameterized-resource
• l2-explicit-parameterized-provider

Note: the tests were failing locally but that was because the local package nugets used in the conformance tests had old contents and needed to be invalidated. This so that pulumi-plugin.json could be filled with the parameterization values.

Where do these logo.png files here come from? Do we really need them?

@tgummerer Technically not required but they are part of SDK gen. We include them to change the icon on nuget.org for Pulumi packages
