[common] Fix ArrayIndexOutOfBoundsException in .toArray() methods

[binary-signal]

Linked issue: close #2157

Purpose

The to*Array() methods in BinaryArray were passing *_ARRAY_OFFSET constants (e.g., DOUBLE_ARRAY_OFFSET) as the targetOffset parameter to BinarySegmentUtils.copyToUnsafe(). These constants are Unsafe memory offsets (typically 16 bytes on 64-bit JVMs), but copyToUnsafe() uses targetOffset as a regular Java array index.

For example, with a 20-element double array:

• targetOffset = DOUBLE_ARRAY_OFFSET ≈ 16
• The code tried to access target[16 + 0] through target[16 + 19 = 35]
• This caused ArrayIndexOutOfBoundsException: Index 20 out of bounds for length 20

Brief change log

Changed all to*Array() methods to pass 0 as the targetOffset since copyToUnsafe() uses regular Java array indexing, not Unsafe memory operations.

Tests

• Added 7 new tests (testTo*ArrayWithLargeArray) that verify all primitive array conversion methods work correctly with 20-element arrays

Here are all the test methods added to BinaryArrayTest.java:

testToDoubleArrayWithLargeArray()
testToFloatArrayWithLargeArray()
testToLongArrayWithLargeArray()
testToIntArrayWithLargeArray()
testToShortArrayWithLargeArray()
testToByteArrayWithLargeArray()
testToBooleanArrayWithLargeArray()
testToDoubleArrayWithLargeArray
