Fixes #19906

Set WINVER and _WIN32_WINNT values in VS project

Fixed possible crash in pck_packer.cpp due to wrong memory freeing.

While looking into a different issue, I've noticed that Visual Studio Intellisense does not work well for Godot project when using Windows Vista+ APIs (e.g. CreateThreadpool), i.e. it does not recognise the APIs because they are defined in Windows header files for Vista+ only.

This is because the WINVER and _WIN32_WINNT symbols don't have their values set in the generated Godot project file. This fixes the problem by setting the values when generating the project file.

WebGL1 some changes

Fixes #25220.

glRenderBufferStorage doesn't accept the _DEPTH_COMPONENT24_OES so I changed it to GL_DEPTH_COMPONENT16

Enabled ext_shader_texture_lod extension. I guess it does the same like the GL_ARB_shader_texture_lod extension, but in WebGL1
https://www.khronos.org/registry/webgl/extensions/EXT_shader_texture_lod/

And last WebGL1 doesn't allow indexes not constant, so I changed it into a loop reading this:
