Resolve host configs at build time (#12792) * Extract base Jest config This makes it easier to change the source config without affecting the build test config. * Statically import the host config This changes react-reconciler to import HostConfig instead of getting it through a function argument. Rather than start with packages like ReactDOM that want to inline it, I started with React Noop and ensured that *custom* renderers using react-reconciler package still work. To do this, I'm making HostConfig module in the reconciler look at a global variable by default (which, in case of the react-reconciler npm package, ends up being the host config argument in the top-level scope). This is still very broken. * Add scaffolding for importing an inlined renderer * Fix the build * ES exports for renderer methods * ES modules for host configs * Remove closures from the reconciler * Check each renderer's config with Flow * Fix uncovered Flow issue We know nextHydratableInstance doesn't get mutated inside this function, but Flow doesn't so it thinks it may be null. Help Flow. * Prettier * Get rid of enable*Reconciler flags They are not as useful anymore because for almost all cases (except third party renderers) we *know* whether it supports mutation or persistence. This refactoring means react-reconciler and react-reconciler/persistent third-party packages now ship the same thing. Not ideal, but this seems worth how simpler the code becomes. We can later look into addressing it by having a single toggle instead. * Prettier again * Fix Flow config creation issue * Fix imprecise Flow typing * Revert accidental changes
