aarch64: vvc: Fix compilation of alf.S with MSVC 2022 17.7 and older 

Use the "ldur" instruction explicitly, instead of having the
assembler implicitly convert "ldr" instructions to "ldur".

This fixes build errors like these:

libavcodec\aarch64\vvc\alf.o.asm(1023) : error A2518: operand 2: Memory offset must be aligned
        ldr             q22, [x3, #24]
libavcodec\aarch64\vvc\alf.o.asm(1024) : error A2518: operand 2: Memory offset must be aligned
        ldr             q24, [x2, #24]
libavcodec\aarch64\vvc\alf.o.asm(1393) : error A2518: operand 2: Memory offset must be aligned
        ldr             q22, [x3, #24]
libavcodec\aarch64\vvc\alf.o.asm(1394) : error A2518: operand 2: Memory offset must be aligned
        ldr             q24, [x2, #24]
