perf: reduce bundle size for Object.keys(import.meta.glob(...))

Description

close #18662

I think we should optimize Object.keys(import.meta.glob / Object.values(import.meta.glob instead of introducing a new query so that users won't need to think about it.
It would be great if rollup or a minifier can optimize this case, but I guess it's easier to do it on our side.

Thanks for your suggestion. But maybe we just need to optimize Object.keys(import.meta.glob, and Object.values(import.meta.glob should follow the original logic.

[btea]

Thanks for the review, the code has been updated.

[sapphi-red]

Thanks! LGTM

The linked issue also requests supporting Object.values, should we not close the issue until that's supported?

[btea]

As far as I understand, Object.values(import.meta.glob('')) can only follow the normal parsing process to get the corresponding object and then get the corresponding values. Are there any other optimization methods here?

[bluwy]

I was thinking that the keys could be minimized, like "0" or "1" instead of paths like "./src/foo.png".

I was also thinking there could be a further optimization in the future where we replace the Object.keys() or Object.values() altogether and directly replace them as an array, but that's harder and we can leave that for later. So if the PR is more of a stop-gap optimization for Object.keys(), maybe we can also do a stop-gap for Object.values().

@bluwy Thanks for the detailed instructions. 👍
