[lldb] Turn off AdbClientTest on windows to fix build breakage (llvm#160771)

llvm#159676 was recently landed.
After it was landed, additional tests were ran, where I saw an assertion
error on windows only. I am not able to test on windows, and the test is
a new test to mock an adb server. The mock server fails to start on
windows, so I am disabling to fix the breakage on main. This is not an
issue with the main code, only a test issue.

Relevant error output:
```
Step 8 (test-check-lldb-unit) failure: Test just built components: check-lldb-unit completed (failure)
