Where I had disabled specific tests due to them being flakey on our
Windows on Arm bot.

Clearly this strategy isn't working because
every day I see a new random test failing.

Until something can be done about this, disable
every lldb-dap test on Windows on Arm. The coverage we get is just not
worth spamming contributors
who have nothing to do with lldb-dap.

Tests that the "scopes" request causes the currently selected
thread and frame to be updated. There are no DAP packets that tell
lldb-dap which thread and frame are selected other than the
"scopes" request. lldb-dap will now select the thread and frame
for the latest "scopes" request that it receives.
The LLDB command interpreter needs to have the right thread and
frame selected so that commands executed in the debug console act
on the right scope. This applies both to the expressions that are
evaluated and the lldb commands that start with the backtick
character.
