sqlite: avoid extra copy for large text binds

[thisalihassan]

Summary

• When binding UTF-8 strings to SQLite statements, transfer ownership of the malloc-backed Utf8Value buffer to SQLite to avoid an extra copy for larger strings.
• Use sqlite3_bind_blob64() for BLOB parameters to avoid truncation for larger payloads.

Benchmarks (local, macOS, Release build)

Compared with base branch (main)

Summary:

• INSERT INTO large_text (text_8kb_column) VALUES (?): *** +5.30% (±1.42%)
• Other insert cases: within ~±1% (not significant), except all_column_types -0.77% (*) (±0.77%)

change primarily improves large text binds; other workloads appear neutral within measurement noise.
