Rename solution, readme and icon files

- Rename NuGet Icon to `Icon.png`:
  - This is no longer used as a public reference point for NuGet icon URL.
  - Also, Icon URL is deprecated. Hence, it's safe to change.

- Normalize casing for `ReadMe.md`:
  - To match the file already in Windows toolkit repo.

- Rename solution file to `CommunityToolkit.sln`:
  - The `dotnet` seems implied and also doesn't stand-out in the file list because of the lower casing and `d` char.
  - Spaces are a main issue when doing automation (_like using `*.sln` in build scripts and in URLs it adds `%20`_).

- Don't exclude T4 Generated sources in git ignores list.
- Indent text in `ThirdPartyNotices.txt` with spaces instead.
