8595: Diagnostic paths support specifying `remapPrefix` r=rickvanprim a=rickvanprim
Currently VSCode Problem Matchers will resolve a path like `//foo_crate/src/main.rs` if `${workspaceFolder}/foo_crate/src/main.rs` exists. Presumably their behavior is functionally a string concatenation that would produce `${workspaceFolder///foo_crate/src/main.rs` and repeated path separators get ignored.
This PR attempts to mimic this behavior by stripping any `Component::RootDir` from `file_name` before joining it to `workspace_root`, and then checking if the file exists. If it does, this path is used, and if not, the behavior falls through to the existing Rust path join behavior.
