Add localPluginPath option to load pre-built plugin in runIde tasks

When localPluginPath is set in gradle.properties, all runIdea, runPyCharm,
runCLion etc. tasks will load the plugin from the specified ZIP file
instead of building from source. This speeds up testing with pre-built
plugin distributions.

Usage: Set localPluginPath=/path/to/plugin.zip in gradle.properties
