Previously python was initialized during static registration of the plugin.
This causes the python interpreter to run even if python support is explicitly
disabled thru:
SBDebugger::SetScriptLanguage(ScriptLanguage::eScriptLanguageNone)
This commit defers python initialization until a ScriptInterpreterPython
instance is created.

Subject: [PATCH] [lldb][NFC] Defer python init until ScriptInterpreter is
created
Previously python was initialized during static registration of the
plugin. This causes the python interpreter to run even if python support
is explicitly disabled thru:
SBDebugger::SetScriptLanguage(ScriptLanguage::eScriptLanguageNone)
This commit defers python initialization until a ScriptInterpreterPython
