…orted Windows projects

This adds the ManifestInfo struct and _create_manifest_info() method to include
a proper Windows application manifest in exported projects. The manifest enables:
- Windows Common Controls 6.0 for proper native dialog appearance
- Long path awareness for Windows 10+

This fixes the "Unable to initialize Windows common controls" warning.

…gine#111316: Remove rcedit dependency for Windows exports (#25)

Backports godotengine#75950, godotengine#108472, and godotengine#111316 to Tekisasu, implementing native PE resource modification for Windows exports.

This eliminates the need for external rcedit tool and wine on non-Windows platforms when modifying Windows executable resources (icons, version info).

Changes
New TemplateModifier class (platform/windows/export/template_modifier.h/.cpp)

Native PE file parsing and modification
Handles icon embedding and version info without external tools
Updated export_plugin.cpp

Replaced _rcedit_add_data() with _add_data() using TemplateModifier
Removed rcedit/wine path validation and subprocess execution
Removed editor settings

export/windows/rcedit
export/windows/wine (non-Windows only)
Removed string remaps for "rcedit" and "wine" in editor_property_name_processor.cpp

Project version fallback (PR godotengine#108472)

Uses get_version() instead of get() for file_version and product_version fields
Enables fallback to project version when version fields are empty in export preset
Application manifest support (PR godotengine#111316)

Added ManifestInfo struct and _create_manifest_info() method
Includes proper Windows application manifest in exported projects
Enables Windows Common Controls 6.0 for native dialog appearance
Enables long path awareness for Windows 10+
Backport Deviations from Godot 4.5+
