Add babel/runtime to dependencies

[garrettjstevens]

Our root babel.config.js uses @babel/transform-runtime. According to the docs here, anything that uses that plugin needs to include @babel/runtime as a dependency. This PR adds that dependency to anything that uses the root babel.config.js.

It also removes the .babelrc files from the individual plugins since @babel/preset-react and @babel/preset-env are already included in the root babel config. It also adds the loose: false option to the root babel config since it was used in the plugin configs.

I noticed this because when I tried to upgrade jbrowse-plugin-apollo to the latest version of @jbrowse/core, I got build errors about not being able to find various babel runtime files. This PR fixes those errors.

this is probably ok. it might be good to modernize our babel config somewhat too e.g. we probably don't need node:8 in babel/env, and we probably don't need to transpile Set/Map to make it necessary to have loose:false ?

[cmdcolin]

I don't know a lot about transform-runtime also but we could even consider removing it

[garrettjstevens]

Turns out we don't need to specify loose: false in the top-level config, since it's the default. It was in the plugin-specific configs to override a TSDX-specific preset, which isn't an issue anymore.

I think it's worth keeping transform-runtime, since it keeps helpers from being added to every file, and our code is spread out over a lot of files.

[cmdcolin]

sounds good :)

[garrettjstevens]

Also, I agree it would be good to modernize the babel config at some point, maybe in a separate PR or PRs.
