Update salsa

[Y-Nak]

This PR updates salsa to salsa 3.0. The major changes are

1. Tracked structs and interned structs are required to have 'db lifetime.
2. The actual Id(or field) of tracked/interned structs is a pointer to a data location now. This means we can't prefill the keyword in salsa 3.0(I simply removed the 'define_keywordmacros. I just removed thefe-macro` crate.
3. We need to implement the salsa::update::Update trait to store a type in another tracked type. In normal cases, we can use salsa::Update derive macro. The only types that I implemented the trait manually are Partial and IndexSet/IndexMap.

Please refer to salsa-rs/salsa#490 for more details.

@micahscopes I decided to leave the lsp crate as is, so it can't be compiled right now. Also, I temporarily excluded the language server crate from the workspace in dce1e09 to build/test the compiler itself. If you have any trouble migrating to salsa 3.0, please let me know.

@g-r-a-n-t This change would affect your driver implementation as well. So please take a quick look at the new driver implementation in this PR.

That's a whole lotta lifetime annotations.
