### Description of changes
This change refactors some of our native iOS and macOS code for better downstream integration into the office codebase.
Namely:
- Every native module's `<Component>-Bridging-Header.h` has been renamed to `<Component>ViewManager.h`.
- These files were never bridging headers, and cocoa pods / swift never interpreted them as such. There is potential to improve the RN docs on how to write a native swift module here as well.
- Adds the `BUILD_LIBRARY_FOR_DISTRIBUTION` flag to each native module's pod spec
- This flag allows for ABI stability in our swift static libraries. Note that the main side effect of this flag is it produces a `.swiftinterface` file in the static libraries' swift module. I do not include the swift module in the NuGet to be included downstream in office. In my testing I found it was not needed to get iOS NativeButton to link, so I opted not to include the swif module. This may change in the future as I try to figure out why the macOS NativeButton static library won't link.
- Adds the `OTHER_SWIFT_FLAGS=-gline-tables-only` flag to each native module's pod spec
- This is a potential security risk that is fixed, as per the comment here https://github.com/microsoft/fluentui-react-native/pull/710#discussion_r688016727 .
- removes the `CLANG_DEBUG_INFORMATION_LEVEL=line-tables-only` build flag
- This caused issues with the previous `BUILD_LIBRARY_FOR_DISTRIBUTION` flag and build failures. I'm not sure why.
- Sets the Swift version to 5.0
- I added this because I noticed that Azure pipelines would actually use the Swift 5.3.2 compiler, so I wanted to be explicit which version of swift we are compiling for.
Prior to this change, we could not link the NativeButton component downstream into office due to some linker issues. This change updates a few parts of our native iOS and macOS code such that we can now link the iOS NativeButton. The macOS NativeButton static library still does not properly link, I'll leave that as a followup.
### Verification
I had a local change downstream in office to consume an intermediate NuGet produced by this PR and test that linking worked. That's where I saw that iOS and not macOS works.
