[lldb-dap] Always pass disableASLR to the DAP executable (llvm#113891)

More context can be found in
llvm#110303

For DAP tests running in constrained environments (e.g., Docker
containers), disabling ASLR isn't allowed. So we set `disableASLR=False`
(since llvm#113593).

However, the `dap_server.py` will currently only forward the value
of `disableASLR` to the DAP executable if it's set to `True`. If the
DAP executable wasn't provided a `disableASLR` field it defaults to
`true` too:
https://github.com/llvm/llvm-project/blob/f14743794587db102c6d1b20f9c87a1ac20decfd/lldb/tools/lldb-dap/lldb-dap.cpp#L2103-L2104

This means that passing `disableASLR=False` from the tests is currently
not possible.

This is also true for many of the other boolean arguments of
`request_launch`. But this patch only addresses `disableASLR` for now
since it's blocking a libc++ patch.
