[Lldb-commits] [lldb] [LLDB][NVIDIA] Add Disassembler log channel (PR #148290)

[Andrew Gontarek via lldb-commits]

https://github.com/agontarek created https://github.com/llvm/llvm-project/pull/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.
