[feature request] Option for installer to download debugging symbols at the installation time and provide instructions on how to make them available for `gdb`

I am installing .NET as `wget https://dot.net/v1/dotnet-install.sh && bash dotnet-install.sh --channel 7.0`

but then one cannot debug a basic SEGFAULTs with `gdb`:

I'm proposing to introduce two command-line options for installer which would:
1. download symbols for all installed `.so` and native binaries - quite common need for dev environment
2. install a debug, unoptimized version of CoreCLR binaries along with symbols

It would also be good to include a `dotnet-symbol` utility by default (especially if it's a small footprint) - it's very useful for dev environment, and figuring that one needs to [`dotnet install` it](https://github.com/dotnet/diagnostics/blob/main/src/Tools/dotnet-symbol/README.md) separately is one more nuisance step :(

Getting some basic stacktraces from gdb right is important (even if SOS tools are only available in lldb)

Thanks!
