Add DELTA and DELTADELTA transform codecs

[xiangfu0]

Context

Stacked on #19285 and part of the split of #18229.

What changed

• Adds DELTA and DELTADELTA as typed-layout-preserving INT/LONG transforms.
• Keeps the output headerless and the same width/count as the input so transforms can be chained before packing or compression.
• Defines intentional two's-complement modular arithmetic for overflow-adjacent values.
• Registers both frozen codec names in the closed runtime registry.
• Makes persisted decoding explicitly big-endian, independent of a caller view's byte order.

Safety and scope

Registering DELTA/DELTADELTA makes them available to the bounded runtime API, but production forward-index creation/loading is not wired until #19307. This slice changes no segment format or production I/O path.

Verification

• INT/LONG round trips for empty, boundary, monotonic, negative, sign-changing, and overflow-adjacent data.
• Allocating and bounded decodeInto paths, transform chains, and malformed-width rejection.
• Stable hand-authored decode fixtures that pin DELTA and DELTADELTA wire bytes independently of the encoders.
• Little-endian caller-view regressions proving big-endian persisted decoding.
• Spotless, Checkstyle, license format, and license check for pinot-segment-local.
