Tomasz Miąsko 5db17335a1 rustdoc: forward -Z options to rustc
Currently rustdoc does not forward `-Z` options to rustc when building
test executables. This makes impossible to use rustdoc to run test
samples when crate under test is instrumented with one of sanitizers
`-Zsanitizer=...`, since the final linking step will not include
sanitizer runtime library.

Forward `-Z` options to rustc to solve the issue.

Helps with #43031.
