scripting — Bazel migration

Targets

Target	Output	Description
//main/scripting:scriptframe	scriptframe.dll	MasterScriptProvider framework (provider + browse-node factory)
//main/scripting:basprov.uno	basprov.uno.dll	Basic script provider
//main/scripting:dlgprov.uno	dlgprov.uno.dll	Dialog provider
//main/scripting:vbaevents.uno	vbaevents.uno.dll	VBA events bridge
//main/scripting:stringresource.uno	stringresource.uno.dll	String resource component
//main/scripting:protocolhandler	protocolhandler.dll	Script protocol handler

Key notes

• All targets need //main/stlport:stlport — source/stringresource/stringresource.hxx, source/provider/ProviderCache.hxx, source/dlgprov/dlgevtatt.hxx, and source/vbaevents/eventhelper.cxx all use std::hash_map from <hash_map>.
• scriptframe sources are listed explicitly (not via glob) because ScriptImpl.cxx and ScriptingContext.cxx exist in source/provider/ but were not in the original nmake SLOFILES list and are not compiled.
• Include paths: /Imain/scripting/inc/pch (for precompiled_scripting.hxx), /Imain/scripting/source/inc (for util/MiscUtils.hxx, bcholder.hxx).
• basprov.uno and dlgprov.uno depend on //main/oovbaapi:oovbaapi_idl_headers for ooo/vba/ UNO-generated headers.
• Java-based scripting providers (scripting/java/, BeanShell, JavaScript) are deferred — Java rules not yet in scope.
