add more pooling allocator options to CLI (#9138)
Browse files Browse the repository at this point in the history
This adds `pooling-table-elements` and `pooling-max-core-instance-size` options
to the CLI, allowing the user to override the defaults.

I found myself needing to override both of these settings when running a ASP.NET
Core application built using the Native AOT feature of the .NET runtime.
