fix(compiler): handle file rename in watch mode

[tanner-reits]

What is the current behavior?

Fixes: #3443

When renaming a file in watch mode, it is possible to run into two errors:

1. A build error resulting from the compiler believing that two components exist with the same tag name (one from the old file name, and one from the new)
2. An HMR issue where the new file name is not correctly registered with the file watcher. So, changes to the renamed file did not trigger an HMR reload

What is the new behavior?

Addresses both of the issues mentioned above by updating the watched files and compiler context whenever a change is detected that triggers the watch callback

N/A

Does this introduce a breaking change?

• Yes
• No

Testing

This is a difficult issue to test (especially the HMR since that was not always consistent), so I was only able to perform manual tests
