Added the ability for the 'default' port version to get a value in case they all change at once (as almost happened due to https://github.com/microsoft/vcpkg/issues/29288)
https://github.com/microsoft/vcpkg/pull/28356/ did not apply post-source stubs for url and locale. I suspect they were just forgotten to be checked in?
https://github.com/microsoft/vcpkg/pull/28617/ did not record the port version change in generate-ports.ps1.
Also fixed all files to have LF line endings. (since changing boost-vcpkg-helper version also changed all the other ports anyway)
Also changed "When changing this file also update and run scripts/boost/generate-ports.ps1" to "Automatically generated by scripts/boost/generate-ports.ps1" because I think that better conveys the consequences (your changes will get nuked).
