To do this we need to carry around the original resolution a bit, because `Self`
gets resolved to the actual type immediately, but you're not allowed to write
the equivalent type in a projection. (I tried just comparing the projection base
type with the impl self type, but that seemed too dirty.) This is basically how
rustc does it as well.
Fixes#3249.
3494: Implement include macro r=matklad a=edwin0cheng
This PR implement builtin `include` macro.
* It does not support include as expression yet.
* It doesn't consider `env!("OUT_DIR")` yet.

3482: Fix regression from #3451 r=matklad a=edwin0cheng
There is a regression from #3451 such that the following code has failed to parse in raw item collecting phase:
```rust
macro_rules! with_std {
($($i:item)*) => ($(#[cfg(feature = "std")]$i)*)
}
with_std! {
mod macros;
mod others;
}
```
### Rationale
We always assume the last token of an statement will not end with a whitespace, which is true. It is because in parsing phase, we always emit `SyntaxNode` before any whitespace. Such that in various parts of RA code, we solely check the semi-colon by using `SyntaxNode::last_child_token() == ";"` .
However, in #3451, we insert some whitespaces between puncts such that we broke above assumption. This PR fixed this bug by make sure we don't add any whitespace if it is a semicolon.

Note that `detail` was replced with `function_signature` to avoid
calling `from` on FunctionSignature twice.
I didn't add new tests because the current ones seem enough.
3429: Fix panic on eager expansion r=matklad a=edwin0cheng
When lazy expanding inside an eager macro, its *parent* file of that lazy macro call must be already exists such that a panic is occurred because that parent file is the eager macro we are processing.
This PR fix this bug by store the argument syntax node as another eager macro id for that purpose.
Personally I don't know if it is a good answer for this bug.
