Add NUCLEO-H7S3L8 BSP

[HiFiPhile]

Describe the PR

Add NUCLEO-H7S3L8 support.

Status:

	FS port	HS port
Device	Unknown	Working
Host	Unknown	*Has issues

* Detach is not detected, resulting _usbh_devices overflow.
* High speed device can't enumerate.

Either not advacning:

Additional context
Wasted 2 hours in EXTI as the offset in SVD file is wrong !
Corrected STM32H7S.svd.zip
