[Windows] Use default aggregate initialization for NVAPI settings

[aitorciki]

Using the member initialization encouraged in NVAPI documentation for NVDRS_SETTING results in builds enabling dev_mode breaking:

platform/windows/gl_manager_windows_native.cpp: In member function 'void GLManagerNative_Windows::_nvapi_setup_profile()':
platform/windows/gl_manager_windows_native.cpp:246:56: error: missing initializer for member '_NVDRS_SETTING_V1::settingName' [-Werror=missing-field-initializers]
  246 |         NVDRS_SETTING ogl_thread_control_setting = { 0 };
      |                                                        ^

Default aggregate initialization results in a clean build though.

Initialy reported by @patwork in #93737 (comment).

@Calinou @akien-mga pinging you directly since this fixes a category of builds broken by a previous PR.
