Previously, we made it possible to compile templates ahead of time as
this was required by the owl devtools. Unfortunately, no effort was made
at the time to make this ahead-of-time compiler outside of the owl repo.
This commit refactors the AoT template compiler by splitting it in two
parts: a typescript module that gets bundled in the dist folder that
gives a programmatic way to call the standalone compiler from another
javascript module by importing it, and a command line utility that is
exposed as an executable files available to npm run-script of dependent
modules (configured in the bin field of owl's package.json).
This allows a simple workflow for modules wanting to use owl:
`npm install @odoo/owl`
add a script to your package.json that calls compile_owl_templates on
your source files, eg:
```jsonc
{
// ...
"scripts": {
"build": "compile_owl_templates src -o dist/templates.js"
}
}
```
`npm run build`
