Blazor: Reorganize files and prepend NationalInstruments namespace

[m-akinc]

Pull Request

🤨 Rationale

For consistency with other NI-authored binaries, we want the Blazor assemblies from this repo to be namespaced under NationalInstruments.

Also, we want to reorganize the Blazor projects to better match the structure of the "components" packages.

👩‍💻 Implementation

• changed namespaces and assembly names from FooBlazor to NationalInstruments.FooBlazor
• moved components .razor and .razor.cs files into component-specific subdirectories
• moved component-specific type files into said directories
• moved shared files from the root into a Components/Patterns directory

🧪 Testing

Build/tests pass

Like the approach and that all the .cs source is in a subfolder since there is a decent amount of other config stuff. Only thought would be renaming the Components root folder to Source since it's not just components but also enums and various utilities. Thoughts or concerns @msmithNI @jattasNI ?

For folders that are nested let's align on the naming conventions in other libraries by not repeating the full parent folder in the name, i.e TableColumn\TableColumnAnchor\ -> TableColumn\Anchor\
