l0rinc 5b74a849cf util: Add consteval ""_hex[_v][_u8] literals ...

""_hex is a compile-time user-defined literal returning std::array<std::byte>, equivalent of ParseHex.

Variants:
- ""_hex_v returns std::vector<std::byte>
- ""_hex_u8 returns std::array<uint8_t>
- ""_hex_v_u8 returns std::vector<uint8_t> - Directly serializable as a size-prefixed OP_PUSH CScript payload using operator<<.

Also extracts from_hex into shared util::ConstevalHexDigit function.
