Use the in-tree compiler-builtins for the sysroot

[tgross35]

Many of std's dependency have a dependency on the crates.io compiler-builtins when used with the feature rustc-std-workspace-core. Use a Cargo patch to select the in-tree version instead.

compiler-builtins is also added as a dependency of rustc-std-workspace-core so these crates can remove their crates.io dependency in the future.

Zulip discussion: #t-compiler > Using in-tree compiler-builtins

Once this merges, the following PRs will need to make it to a release for the relevant crates:

• Bump unicode-width to 0.2.0 getopts#119 (can merge at any time)
• Remove optional dependency on compiler-builtins hashbrown#625 (can merge at any time)
• Remove compiler-builtins from rustc-dep-of-std dependencies stdarch#1825
• Remove compiler-builtins from rustc-dep-of-std dependencies rustc-demangle#80
• Remove compiler-builtins from rustc-dep-of-std dependencies cfg-if#84
• Remove compiler-builtins from rustc-dep-of-std dependencies unicode-rs/unicode-width#77

The above should cover all tier 1 targets with no std features enabled. The remaining cover the rest:

• Remove compiler-builtins from rustc-dep-of-std dependencies alexcrichton/dlmalloc-rs#50 (wasm, xous, sgx)
• Remove compiler-builtins from rustc-dep-of-std dependencies gimli-rs/gimli#769
• Remove compiler-builtins from rustc-dep-of-std dependencies r-efi/r-efi#89 (efi)
• Remove compiler-builtins from rustc-dep-of-std dependencies r-efi/r-efi-alloc#9 (efi)
• Remove compiler-builtins from rustc-dep-of-std dependencies fortanix/rust-sgx#770 (sgx)
• Remove compiler-builtins from rustc-dep-of-std dependencies hermit-os/hermit-rs#718 (hermit)
• Remove compiler-builtins from rustc-dep-of-std dependencies bytecodealliance/wasi-rs#108 (wasi)
• Remove compiler-builtins from rustc-dep-of-std dependencies gimli-rs/addr2line#345

I believe this works now. The first two commits are cherry picks that I will drop once #142036 merges.

@rust-lang/cargo @rust-lang/rust-analyzer does anyone have a rough idea of what changes, if any, would be needed with this PR to keep from breaking -Zbuild-std and R-A's building of the sysroot? The relevant part is that a new (hopefully short lived) patch item in library/Cargo.toml would be required.

@ehuss was able to verify this didn't seem to break Cargo things: https://rust-lang.zulipchat.com/#narrow/channel/246057-t-cargo/topic/Testing.20with.20a.20specific.20rust-lang.2Frust.20PR/with/522678293
