wifi: mt76: mt7925: introduce MLO capability control 



This patch introduces MLO capability control for the MT792x Wi-Fi driver.
It removes the unused `MT792x_CHIP_CAP_MLO_EVT_EN` flag and introduces new
capability flags `MT792x_CHIP_CAP_MLO_EN` and `MT792x_CHIP_CAP_MLO_EML_EN`
to enable MLO and EML features based on firmware capabilities.
