[LLDB][NVIDIA] Add Disassembler log channel (#148290)
This commit introduces a new log channel for the disassembler in LLDB,
allowing for better logging of disassembler related activities. The
`LLDBLOG` enum has been updated to include the `Disassembler` channel,
and the relevant logging in the `DisassemblerLLVMC` plugin has been
modified to utilize this new channel. This is in preparation for adding
additional disassembler implementations.
Key Changes:
- Added `Disassembler` to the `LLDBLog` enum.
- Updated logging in `DisassemblerLLVMC.cpp` to use the new
`Disassembler` log channel.
