[GLUTEN-12044][CH] Fix build on arm

[zhanglistar]

What changes are proposed in this pull request?

Fix issue #12044.
Fix an ARM64/NEON build failure in LocalDigitsToAsciiDigitForDate. The previous implementation called simd8_u8::load(...).is_ascii(), but on ARM64 the simdjson simd8<uint8_t>::load returns the underlying vector type, so the member call is invalid.

This PR replaces the ASCII check with a portable SIMD predicate using any_bits_set_anywhere(simd8_u8(0x80)) to detect any byte with the high bit set, preserving the original intent while compiling across SIMD backends.

How was this patch tested?

• Rebuilt the failing object/target in the ARM64 cross-compilation environment and confirmed it compiles successfully.
• (Optional) Ran a full build to ensure no regressions.
