`esbuild-kit/tsx` support

[fregante]

esbuild-kit/tsx is a popular Node/TypeScript loader based on esbuild.

I'd like to use this loader because it's the most straightforward I found so far, without issues and verbose configuration. I wish this was supported natively in Webpack and it looks like Webpack uses interpret internally to automatically load its config.

This is currently supported via experimental flags, up to Node 18:

cross-env NODE_OPTIONS="--loader tsx" webpack --mode=production

But interpret already supports a number of loaders without any config, as shown by this error message:

[webpack-cli] Unable load './webpack.config.ts'
[webpack-cli] Unable to use specified module loaders for ".ts".
[webpack-cli] Cannot find module 'ts-node/register' from '.'
[webpack-cli] Cannot find module 'sucrase/register/ts' from '.'
[webpack-cli] Cannot find module '@babel/register' from '.'
[webpack-cli] Cannot find module 'esbuild-register/dist/node' from '.'
[webpack-cli] Cannot find module '@swc/register' from '.'
[webpack-cli] Please install one of them

I'm adding a bounty of $20 to this issue, to be paid when the feature ships to NPM.

CC @evenstensberg since you have an open PR.

CC @privatenumber - this would add tsx support to over 1000 projects, including webpack

@phated @errorx666 I've finished the PR for supporting tsx.

FYI there's already a PR: #96
