Add pluggable page-level AEAD encryption support

[HTHou]

Summary

• add an optional file encryption header carrying provider, profile, key, wrapped data key, and file identity metadata
• introduce a provider-neutral AEAD SPI and registry without embedding a concrete cryptographic implementation
• encrypt compressed page bodies for non-aligned, aligned, and table-model write paths, and decrypt them on the corresponding read paths
• preserve existing unencrypted TsFile behavior and propagate encryption metadata through append, recovery, lazy loading, and sketch tooling
• add compatibility, round-trip, tamper-detection, append, and recovery tests

Motivation

TsFile currently has legacy encryption interfaces but no self-describing file-level context for pluggable page-level authenticated encryption. This change establishes the format and I/O integration points while leaving algorithm and key-management implementations to external providers.

Compatibility

• Existing unencrypted TsFiles keep their current layout and remain readable.
• Encrypted files require a registered provider matching the identifiers stored in the encryption header.
• Page metadata remains readable while compressed page bodies are protected with AEAD.
• The encrypted-file format and public API are still under discussion and are not intended as a compatibility commitment in this draft.

Validation

• ./mvnw spotless:check -P with-java -pl java/tsfile -am
• ./mvnw test -P with-java -pl java/tsfile -am -Dtest='PageCryptoContextTest,FileEncryptionHeaderTest,TDEPageAeadTsFileTest,UnClosedTsFileReaderTest,ForceAppendTsFileWriterTest,RestorableTsFileIOWriterTest,TimePageWriterTest' -Dsurefire.failIfNoSpecifiedTests=false
• 30 targeted tests passed with no failures or errors

Draft discussion points

• finalize the encryption-header schema and format-version semantics
• bind page authentication data to an unambiguous chunk/page identity
• refine page-index ownership and the separation between legacy encryption parameters and file AEAD context
• confirm append/recovery behavior and backward-compatibility expectations before stabilizing the format
