Synthesize namespace records for proper esm interop (#19675) * Integrate importStar and importDefault helpers * Accept baselines * Support dynamic imports, write helpers for umd module (and amd is possible) kinds * Accept baselines * Support AMD, use same helper initialization as is normal * update typechecker to have errors on called imported namespaces and good error recovery with a quickfix * Overhaul allowSyntheticDefaultExports to be safer * Put the new behavior behind a flag * Rename strictESM to ESMInterop * ESMInterop -> ESModuleInterop, make default for tsc --init * Rename ESMInterop -> ESModuleInterop in module.ts, add emit test (since fourslash doesnt do that) * Remove erroneous semicolons from helper * Reword diagnostic * Change style * Edit followup diagnostic * Add secondary quickfix for call sites, tests forthcoming * Add synth default to namespace import type, enhance quickfix * Pair of spare tests for good measure * Fix typos in diagnostic message * Improve comment clarity * Actually accept the updated changes to the esmodule interop description * ESModule -> esModule * Use find and not forEach * Use guard * Rely on implicit falsiness of Result.False * These should have been emit flags 2018-01-09 01:36:23 +01:00			`// @esModuleInterop: true`
