fix: execute classic worker in dev mode

[poyoho]

Description

fix: #4586
fix: #5853
fix: #7019
close: #6973

Additional context

Detect the case where { type: 'module' } is not provided or { type: 'classic' } is passed with a static string and use classic workers. If a dynamic expression appears, we can issue an error. And give /* @vite-ignore */ out of Vite processing.

1. we should throw the dynamic worker type error, so we should find the all worker options.
2. use re match worker type for avoid the situation that json5 cannot parse functions call string.
3. dynamic worker options type we can't know how import the env so don't inject the env in dev mode, but build mode it also be replaced.

I'm not the most familiar with workers, but I'm not sure if we want to introduce a special @vite-ignore comment here. That would be non-standard and prone to errors, e.g. some tooling strips comments.

For dynamic cases, I think Vite should just ignore it without an error, and preserve the user code as is? 🤔

Edit: Ah looks like @patak-dev suggested something similar at #7019 (comment)

I think user can't to write code compatible classic worker and module worker When I write the test case for dynamic worker.
The dynamic worker may only happen in user accidentally passed in the variable. So I think the error report is reasonable.

But vite can automatically ignore this worker file, so it only needs warning.

"Exceeded timeout of 30000 ms for a test.

I don't know why got a error in unit test

🤕 import * as JSON5 from 'json5' is work in my machine.

Looks good to me. Let's wait for the 2.9 beta to merge it to get some testing.

@ygj6 would you help reviewing this PR?

I modify your method(getEndIndex), in this case it will got a error.

/* ) */ ) 
// comment 

it will got a single comment index and the endIndex no in the single comment, return a error value(index of multiline comment ))

so I use the small index to matched.
