[ASan][windows] Recognize movzx r11d, BYTE PTR [rdx] in interception_win (#111638)
The instruction is present in some library in the 24H2 update for
Windows 11:
==8508==interception_win: unhandled instruction at 0x7ff83e193a40: 44 0f
b6 1a 4c 8b d2 48
This could be generalized, but getting all the ModR/M byte combinations
right is tricky. Many other classes of instructions handled in this file
could use some generalization too.
