Add brush-shell 0.3.0 to third-party Rust crates

Summary:
allow-large-files

Import brush-shell 0.3.0 (https://github.com/reubeno/brush), a bash/POSIX-compatible
shell implemented in Rust. This adds brush-shell and its transitive dependencies
(brush-core, brush-builtins, brush-parser, brush-interactive, uucore, etc.).

Fixups created:
- brush-core: cargo_env for CARGO_PKG_VERSION_{MAJOR,MINOR,PATCH}
- brush-shell: overlay to replace env!("CARGO_PKG_HOMEPAGE") (unsupported by reindeer)
  with env!("CARGO_PKG_REPOSITORY"), and to remove git_version! macro usage
- uucore: buildscript.run = true with CARGO_MANIFEST_DIR

Placed in cfg(linux(x86_64,aarch64) + macos + windows) section since brush-core
requires tokio signal/process features which are omitted on embedded platforms.
