Rollup merge of #65603 - mystor:resolve_path_ice, r=petrochenkov

Avoid ICE when include! is used by stdin crate

This should hopefully also eliminate the ICE when using `include_bytes!`, `include_str!` and `#[doc(include = "...")]` with a stdio input.

I couldn't see a clear way to write a compile-fail test using compiletest with a stdio input, so I haven't written any tests for this change.

Fixes #63900
