Revert of Correctly annotate eval origin. (patchset #4 id:60001 of https://codereview.chromium.org/1854713002/ )

Browse Source 
Reason for revert:
[Sheriff] Crashes a layout test:
https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2064/builds/5855

Original issue's description:
> Correctly annotate eval origin.
>
> There were a couple of issues with it:
> - interpreter is not supported
> - the source position was just accidentally correct for full-codegen
> - the eval origin could have been cached
>
> Also fixes a few other places to use AbstractCode.
