(feat) Add basic mimxrt support.

[andrewleech]

I'm working on getting LVGL working cleanly on the NXP 1170 EVK with a LVGL v9 compatible driver in progress here: https://github.com/andrewleech/imxrt1170_display_driver

These minimal changes to the LVGL bindings files enables the build environment to enable port specific features more easily.

Summary by cubic

Add basic NXP i.MX RT (mimxrt) support by enabling port-specific LVGL GPU/PXP configuration and wiring build flags for the mimxrt port. This allows LVGL v9 to run on the RT1170 EVK with PXP acceleration.

• New Features
  • Detect the active port in micropython.mk and add a mimxrt block that enables LV_USE_PXP, LV_USE_DRAW_PXP, LV_USE_GPU_NXP_PXP, and LV_USE_GPU_NXP_PXP_AUTO_INIT.
  • Make LV_USE_DRAW_VGLITE and LV_USE_PXP overridable in lv_conf.h so ports can turn these on without editing the config.
  • Suppress specific compiler warnings for PXP files to keep the mimxrt build clean.

LV_USE_PXP is still the controlling flag for this block, but the new guard defines LV_USE_DRAW_PXP instead, leaving LV_USE_PXP undefined so the feature can never be enabled.
