[lldb] Inherit Host::GetEnvironment() when launching a wasm runtime (#190476)

Browse Source 
Some WebAssembly runtimes might use environment variables such as `HOME`
or `XDG_CONFIG_HOME` to store configuration files, additionally some VMs
might allow wasm modules to read environment variables from the host.
Currently, if a runtime is launched using the WebAssembly platform it
doesn't inherit the environment. As a result wasm runtimes and modules
are unable to read from environment variables and might even fail to
launch (if the config file is required). This PR aims to resolve this
issue, I have tested this with the WARDuino runtime and my WIP gdbstub.
