The motivation here is that we don't want to pollute the SBAPI with getters/setters for expression evaluation options that only apply to a single language. The ultimate goal would be to have plugins register additional options to the `expression` command when the plugin is loaded. This patch only provides the minimal `SBExpressionOptions` interface to set an option with an arbitrary name, which the language plugin knows how to interpret. The underlying options dictionary is an `StructuredData::Dictionary` so we can map strings to values of any type. But the SBAPI just exposes setting a boolean value. Future overloads of `SetLanguageOption` can provide setters for more types. The boolean setter/getter will be used for the C++-specific option being introduced in: https://github.com/llvm/llvm-project/pull/177926
