[lldb] Suppress unsupported language warning for assembly (#95871)

The following warning is technically correct, but pretty much useless,
since there aren't any frame variables that we'd expect the debugger to
understand.

> This version of LLDB has no plugin for the language "assembler".
> Inspection of frame variables will be limited.

This message is useful in the general case but should be suppressed for
the "assembler" case.
