The hex_encode() and hex_decode() functions serve as the workhorses for hexadecimal data for bytea's text format conversion functions, and some workloads are sensitive to their performance. This commit adds new implementations that use routines from port/simd.h, which testing indicates are much faster for larger inputs. For small or invalid inputs, we fall back on the existing scalar versions. Since we are using port/simd.h, these optimizations apply to both x86-64 and AArch64.
