8776: fix: fix unnecessary recomputations due to macros r=jonas-schievink a=jonas-schievink
This computes a macro's fragment kind eagerly (when the calling file is still available in parsed form) and stores it in the `MacroCallLoc`. This means that during expansion we no longer have to reparse the file containing the macro call, avoiding the unnecessary salsa dependencies (https://github.com/rust-analyzer/rust-analyzer/pull/8746#issuecomment-834776349).
Marking as draft until I manage to find a test for this problem, since for some reason `typing_inside_a_function_should_not_invalidate_expansions` does not catch this (which might indicate that I misunderstand the problem).
I've manually confirmed that this fixes the issue described in https://github.com/rust-analyzer/rust-analyzer/pull/8746#issuecomment-834776349:
```
7ms - parse_query @ FileId(179)
12ms - SourceBinder::to_module_def
12ms - crate_def_map:wait
5ms - item_tree_query (1 calls)
7ms - ???
```

8777: Escape characters in builtin macros correctly r=edwin0cheng a=edwin0cheng
Fixes#8749
It is the same bug in #8560 but in our `quote!` macro.
Because the "\" are adding exponentially in #8749 case, so the text is eat up all the memory.

8774: feat: Honor `.cargo/config.toml` r=matklad a=Veykril
Implements `cargo/.config` build target and cfg access by using unstable cargo options:
- `cargo config get` to read the target triple out of the config to pass to `cargo metadata` --filter-platform
- `cargo rustc --print` to read out the `rustc_cfgs`, this causes us to honor `rustflags` and the like.
If those commands fail, due to not having a nightly toolchain present for example, they will fall back to invoking rustc directly as we currently do.
I personally think it should be fine to use these unstable options as they are unlikely to change(even if they did it shouldn't be a problem due to the fallback) and don't burden the user if they do not have a nightly toolchain at hand since we fall back to the previous behaviour.
