Issue body
Several plugins within Snapcraft support parallel builds, but Snapcraft currently doesn't take advantage of this and builds them with a single job. This PR resolves LP: [#1551417](https://bugs.launchpad.net/snapcraft/+bug/1551417) by adding support for parallel builds, and enabling them by default in the autotools, cmake, and make plugins. It also adds an option to disable parallel builds via the `--no-parallel-build` option for the case of running in a RAM-limited environment.

| #1551417 Support parallel builds | snapcraft (launchpad) | closed | Parallel autotools, CMake, and make builds were enabled by default with a --no-parallel-build opt-out via merged PR #357 (commit 35cd5ca2c). | |
| #1167 feat: add parallel parameter to autotools plugin | craft-parts | merged | Merged #1167 as commit 7dfd1bf7, adding disable_parallel to the Autotools plugin so builds can omit make -j and addressing #1069. | |
| #1608994 Need a way to disable parallel building per part | snapcraft (launchpad) | closed | Per-part parallel-build control was added by merged PR #698 (commit b7fc3eb66), which introduced the disable-parallel plugin property; the autotools plugin later gained it (commit 634d72466), documented in the 8.13 release notes. | |
| #1242 make plugin: Support `disable-parallel` parameter | craft-parts | open | Enhancement: make plugin should honor the disable-parallel part property (currently always emits make -j"N"). Filed by a maintainer, labeled Triaged/Enhancement, and explicitly deferred as "extremely low priority" until a real-world non-parallel-build use case is supplied; autotools already has it via PR #1167. | |
| #2733 cmake plugin: support disable-parallel option | snapcraft | merged | Merged in canonical/snapcraft#2733 (commit 634d72466), enabling CMake disable-parallel via BasePlugin's parallel build count and adding unit coverage. | |
| #1631 docs: document autotools disable-parallel key | craft-parts | open | Docs-only PR adding the autotools `disable-parallel` key and a parallel-build note plus a changelog entry to the Autotools plugin reference. Approved by one reviewer but 2 unresolved comments remain; author agreed to revert the "How it works" line and awaits maintainer guidance; 3 CI checks failing. |
