[Lldb-commits] [lldb] Revert "[lldb] Make sure the process is stopped when computing the symbol context (#134757)" (PR #135408)

[Jonas Devlieghere via lldb-commits]

https://github.com/JDevlieghere created https://github.com/llvm/llvm-project/pull/135408

This reverts commit e84a80408523a48d6eaacd795f1615e821ffb233 because on Linux there seems to be a race around GetRunLock. See #134757 for more context.
