x64: failure to disassemble LIDT instructions

[sad-dev]

Describe the bug
The following are several (de-duped) byte patterns that Ghidra fails to disassemble on an x64 program, with corresponding disassembly from Capstone/IDA

0f 01 9d 98 01 00 00
lidt [rbp + 0x198]

0f 01 9f f6 00 00 00
lidt [rdi + 0xf6]

0f 01 59 66
lidt [rcx + 0x66]

0f 01 5d f7
lidt [rbp - 9]

This is an issue with the constructors for the LIDT instruction. The 64-bit versions are specifying an opsize of 64, but the default opszize is 32 for 64-bit. The opsize parameter should be removed.

The SIDT instruction is also wrong here - it's using the 32-bit version, not the 64-bit version. It doesn't have the $(LONGMODE_OFF) restriction (but it should), and the opsize=2 should be removed from the 64-bit version.
