This makes it possible to have both std::panic and core::panic as a builtin macro, by using different builtin macro names for each. Also removes SyntaxExtension::is_derive_copy, as the macro name (e.g. sym::Copy) is now tracked and provides that information directly.

This used to be necessary for `is_builtin` in the past, but is no longer required. Co-authored-by: Vadim Petrochenkov <vadim.petrochenkov@gmail.com>

…=petrochenkov Allow #[rustc_builtin_macro = "name"] This adds the option of specifying the name of a builtin macro in the `#[rustc_builtin_macro]` attribute: `#[rustc_builtin_macro = "name"]`. This makes it possible to have both `std::panic!` and `core::panic!` as a builtin macro, by using different builtin macro names for each. This is needed to implement the edition-specific behaviour of the panic macros of RFC 3007. Also removes `SyntaxExtension::is_derive_copy`, as the macro name (e.g. `sym::Copy`) is now tracked and provides that information directly. r? `@petrochenkov`

resolve: Simplify built-in macro table We don't use full `SyntaxExtension`s from the table, only `SyntaxExtensionKind`s, and `Ident` in `register_builtin_macro` always had dummy span. This PR removes unnecessary data from the table and related function signatures. Noticed when reviewing rust-lang#80850.
