Harmonize errors thrown in @lwc/ssr-compiler

[nolanlawson]

In principle, ssr-compiler should throw exactly the same error messages as babel-plugin-component, template-compiler, etc. for the same input. These errors are defined in @lwc/errors and are designed to be shared.

For expediency, we have not yet used the correct error messages in ssr-compiler. We should.

These errors should ideally also have some way to bubble up the row/column number that caused the error, so that it can be integrated with the VS Code extension.

What do you think about reusing the tests (only the ones with error.json) from babel-plugin-component? There are too many possible errors and different scenarios.

[nolanlawson]

@cardoso This is effectively what I did – I copy-pasted some of the tests. I'm a bit on-the-fence about explicitly sharing the test files, though. There aren't that many scenarios, and in a normal environment (including Salesforce), if you get an error for CSR compilation, then your SSR compilation will fail as well.
