Can we remove the global definition behind the BABEL_8_BREAKING flag?

It is more appropriate to use var like runtime helpers, otherwise, this code needs to be compiled into es5 with babel self 👀

Even if
@babel/runtime' was documented as being a pure set of helpers and the@babel/runtime/regeneratorentry point exported theregeneratorRuntimehelper, it also accientally used to define aregeneratorRuntimeglobal due to its depenency onregenerator-runtime`.Many packages relied on this global being "accidentally" present due to something else in the dependencies tree loading
@babel/runtime/regenerator. I'm annoyed by this, but let's restore the old (accidental and undocumented) behavior because I have already seen multiple repositories with this problem. We'll remove this legacy entry point in Babel 8.Closes #14576.
