[jdk21u-dev] RFR: 8324858: [vectorapi] Bounds checking issues when accessing memory segments

[Aleksey Shipilev]

Clean backport to fix the preview feature. This helps users to detect out of bounds before they break important applications, or fail to work in production-ready version of Vector API. There were some conflicts in copyright years, which I resolved by fixing the templates and regenerating the tests.

Additional testing:
 - [x] macos-aarch64-server-fastdebug, `jdk/incubator/vector`
 - [x] linux-aarch64-server-fastdebug, `jdk/incubator/vector`
 - [x] linux-x86_64-server-fastdebug, `jdk/incubator/vector`
 - [x] linux-aarch64-server-fastdebug, `tier{1,2,3,4}`
