[win/asan] GetInstructionSize: Support `48 bX` movabsq instructions. (#141625)
Created for Wine's memset by clang or mingw-gcc,
the latter places it quite at the start of the function:
```
0x00006ffffb67e210 <memset+0>: 0f b6 d2 movzbl %dl,%edx
0x00006ffffb67e213 <memset+3>: 48 b8 01 01 01 01 01 01 01 01 movabs $0x101010101010101,%rax
```
`3200 uint64_t v = 0x101010101010101ull * (unsigned char)c;`
