Rollup merge of #131926 - clubby789:configure-enable, r=Kobzol

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:

```

        --enable-debug                     OR --disable-debug
                enables debugging environment; does not affect optimization of bootstrapped code
        --enable-docs                      OR --disable-docs

        --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

        --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
