Should we fallback to ts.transpileModule whenever we get "Emit skipped"?

Seems like a bit of a hack, but it means certain situations "just work." If the file is statically imported, then it's already being typechecked. The only limitation is that transpileOnly needs isolatedModules, so if projects rely on rare things like inlined const enumeration values, that'll fail. But otherwise seems like a win.

Would fix #693

**Added**

-   Eliminate "Emit Skipped" errors ([#&#8203;693](TypeStrong/ts-node#693), [#&#8203;1345](TypeStrong/ts-node#1345), [#&#8203;1629](TypeStrong/ts-node#1629))
    -   Avoids all "Emit Skipped" errors by performing a fallback `transpileOnly`-style transformation.
    -   Does not affect typechecking.  Type errors are still detected and thrown.
    -   Fallback has the same limitations as `isolatedModules`. This will only affect rare cases such as using `const enums` with `preserveConstEnums` disabled.
    -   Fixes [#&#8203;693](TypeStrong/ts-node#693)
-   Graduate swc transpiler out of experimental; add `swc: true` convenience option ([docs](https://typestrong.org/ts-node/docs/transpilers)) ([#&#8203;1487](TypeStrong/ts-node#1487), [#&#8203;1536](TypeStrong/ts-node#1536), [#&#8203;1613](TypeStrong/ts-node#1613), [#&#8203;1627](TypeStrong/ts-node#1627))
    -   `"swc": true` or `--swc` will use swc for faster execution
    -   This feature is no longer marked "experimental."  Thank you to everyone who filed bugs!
-   swc transpiler attempts to load `@swc/core` or `@swc/wasm` dependencies from your project before falling-back to global installations ([#&#8203;1613](TypeStrong/ts-node#1613), [#&#8203;1627](TypeStrong/ts-node#1627))
    -   global fallback only occurs when using a global installation of ts-node
-   Add support for TypeScript's `traceResolution` output ([docs](https://www.typescriptlang.org/tsconfig/#traceResolution)) ([#&#8203;1128](TypeStrong/ts-node#1128), [#&#8203;1491](TypeStrong/ts-node#1491)) [@&#8203;TheUnlocked](https://github.com/TheUnlocked)
-   Support import assertions in ESM loader ([docs](https://nodejs.org/dist/latest-v17.x/docs/api/esm.html#import-assertions)) ([#&#8203;1557](TypeStrong/ts-node#1557), [#&#8203;1558](TypeStrong/ts-node#1558), [#&#8203;1559](TypeStrong/ts-node#1559), [#&#8203;1573](TypeStrong/ts-node#1573)) [@&#8203;Pokute](https://github.com/Pokute), [@&#8203;geigerzaehler](https://github.com/geigerzaehler)
    -   Allows importing JSON files from ESM with the requisite flag ([docs](https://nodejs.org/dist/latest-v17.x/docs/api/esm.html#json-modules))
-   `ts-node -vvv` also logs absolute paths to `ts-node` and `typescript`, to make it more obvious when you're accidentally using globally-installed versions ([#&#8203;1323](TypeStrong/ts-node#1323), [#&#8203;1620](TypeStrong/ts-node#1620))
-   Add swc target "es2022" ([#&#8203;1535](TypeStrong/ts-node#1535), [#&#8203;1540](TypeStrong/ts-node#1540))
    -   When you have target es2022 in tsconfig, will use swc's es2022 target

**Changed**

-   Initialize TypeScript compiler before starting REPL prompt ([#&#8203;1498](TypeStrong/ts-node#1498)) [@&#8203;TheUnlocked](https://github.com/TheUnlocked)
    -   Improves responsiveness for first line of REPL input
-   Use `v8-compile-cache-lib` to load typescript
    -   improves startup time ([#&#8203;1339](TypeStrong/ts-node#1339), [#&#8203;1603](TypeStrong/ts-node#1603))
-   Support both `--camelCase` and `--hyphen-case` for all CLI flags; update documentation to use `--camelCase` ([#&#8203;1598](TypeStrong/ts-node#1598), [#&#8203;1599](TypeStrong/ts-node#1599))
    -   Not a breaking change; CLI continues to accept both forms
-   Make `TSError` `diagnosticText` property non-enumerable to prevent it from being logged below the stack ([#&#8203;1632](TypeStrong/ts-node#1632))

**Fixed**

-   Fix [#&#8203;1389](TypeStrong/ts-node#1389): In `--showConfig` output, emit accurate `moduleTypes` paths resolved relative to the `tsconfig.json` which declared them ([#&#8203;1389](TypeStrong/ts-node#1389), [#&#8203;1619](TypeStrong/ts-node#1619))
-   Fix: Remove indentation from `ts-node --help` output ([#&#8203;1597](TypeStrong/ts-node#1597), [#&#8203;1600](TypeStrong/ts-node#1600))
-   Fix [#&#8203;1425](TypeStrong/ts-node#1425): Merged definitions correctly into `tsconfig.schemastore-schema.json` ([#&#8203;1425](TypeStrong/ts-node#1425), [#&#8203;1618](TypeStrong/ts-node#1618))
-   Fix: Allow disabling `"use strict"` emit in SWC transpiler ([#&#8203;1531](TypeStrong/ts-node#1531), [#&#8203;1537](TypeStrong/ts-node#1537))
-   Fix: Add missing `ERR_UNKNOWN_FILE_EXTENSION` constructor; was throwing `ERR_UNKNOWN_FILE_EXTENSION is not a constructor` ([#&#8203;1562](TypeStrong/ts-node#1562)) [@&#8203;bluelovers](https://github.com/bluelovers)
-   Fix [#&#8203;1565](TypeStrong/ts-node#1565): entrypoint resolution failed on node v12.0.x and v12.1.x ([#&#8203;1565](TypeStrong/ts-node#1565), [#&#8203;1566](TypeStrong/ts-node#1566)) [@&#8203;davidmurdoch](https://github.com/davidmurdoch)
