Feature request: Make COMPILATIONDB_INCLUDE_TOOLCHAIN as compiledb flag

[jayadamsmorgan]

I am working with a lot of projects and my main IDE isn't VSCode, so I need compilation database to be generated for every project so the LSP would work. The problem is that every time I create/edit project I need to add script which will enable COMPILATIONDB_INCLUDE_TOOLCHAIN. In most cases I don't even need build scripts for anything else besides enabling this flag. I thought maybe it's a good idea to include this flag in pio run command? ( e.g. pio run -t compiledbtc (?) )
