Align boolean option descriptions in `configure.py`
Boolean options are currently printed as
```
Options
--enable-debug OR --disable-debug enables debugging environment; does not affect optimization of bootstrapped code
--enable-docs OR --disable-docs build standard library documentation
--enable-compiler-docs OR --disable-compiler-docs build compiler documentation
--enable-optimize-tests OR --disable-optimize-tests build tests with optimizations
--enable-verbose-tests OR --disable-verbose-tests enable verbose output when running tests
--enable-ccache OR --disable-ccache invoke gcc/clang via ccache to reuse object files between builds
--enable-sccache OR --disable-sccache invoke gcc/clang via sccache to reuse object files between builds
--enable-local-rust OR --disable-local-rust use an installed rustc rather than downloading a snapshot
--local-rust-root=VAL set prefix for local rust binary
--enable-local-rebuild OR --disable-local-rebuild assume local-rust matches the current version, for rebuilds; implies local-rust, and is implied if local-rust already matches the current version
```
as of #131117
imo, this is a little difficult to skim. This PR changes this to align the `OR`s and push the description onto a newline:
```
Options
--enable-debug OR --disable-debug
enables debugging environment; does not affect optimization of bootstrapped code
--enable-docs OR --disable-docs
build standard library documentation
--enable-compiler-docs OR --disable-compiler-docs
build compiler documentation
--enable-optimize-tests OR --disable-optimize-tests
build tests with optimizations
--enable-verbose-tests OR --disable-verbose-tests
enable verbose output when running tests
--enable-ccache OR --disable-ccache
invoke gcc/clang via ccache to reuse object files between builds
--enable-sccache OR --disable-sccache
invoke gcc/clang via sccache to reuse object files between builds
--enable-local-rust OR --disable-local-rust
use an installed rustc rather than downloading a snapshot
--local-rust-root=VAL set prefix for local rust binary
--enable-local-rebuild OR --disable-local-rebuild

```
This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
