Proc macro span API redesign: Replace proc_macro::SourceFile by Span::{file, local_file}
Simplification/redesign of the unstable proc macro span API, tracked in https://github.com/rust-lang/rust/issues/54725:
Before:
```rust
impl Span {
pub fn line(&self) -> usize;
pub fn column(&self) -> usize;
pub fn source_file(&self) -> SourceFile;
}
#[derive(Clone, Debug, PartialEq, Eq)]
pub struct SourceFile { .. }
impl !Send for SourceFile {}
impl !Sync for SourceFile {}
impl SourceFile {
pub fn path(&self) -> PathBuf;
pub fn is_real(&self) -> bool;
}
```
After:
```rust
impl Span {
pub fn line(&self) -> usize;
pub fn column(&self) -> usize;
pub fn file(&self) -> String; // Mapped file name, for display purposes.
pub fn local_file(&self) -> Option<PathBuf>; // Real file name as it exists on disk.
}
```
This resolves the last blocker for stabilizing these methods. (Stabilizing will be a separate PR with FCP.)
