  [vscode-lldb] Support lldb-dap environment in debug configuration (#153536)

# Changes
1. Add a new debug configuration field called `debugAdapterEnv`. It accepts a string-valued dictionary or array.
    1. This input format is consistent with the (program's) `env` debug configuration.
2. In the adapter descriptor factory, honor the said field before looking at the VS Code settings `Lldb-dap: Environment `.
    1. This order is consistent with how things are done for other debug configuration fields, e.g. lldb-dap path and args.
3. In the lldb-dap server, note down the environment entries as a part of the adapter spawn info (now it becomes "path + args + env"), and prompt the user to restart server if such info has changed.

# Motivation
1. Adapter environment can be set in `launch.json`.
2. Other debugger extensions can invoke the lldb-dap extension with adapter environment (via debug configuration).

# Tests
See PR #153536.
