boards: gd32e507z_eval: add initial support

[gmarull]

Add initial support for the GD32E507Z-EVAL board. Only basic peripherals
are enabled for now:

• UART
• GPIO (LEDs, keys)
• PWM

Others, e.g. I2C, EEPROM, DAC, etc. require further testing and likely
some driver adjustments.

Can't test on the board itself, but all looks good.

Probably not related with PR but I couldn't test PyOCD. Any tips?

@nandojve looks like you don't have the CMSIS-Pack correctly installed. I can flash it:

I managed to make it work but I still have few problems. Anyway, definitely it is something with my Debian.
Thank you for the tip.

@gmarull can you rebase?

Failed tests are unrelated (qemu_x86_64: kernel, qemu_x86: logging ).
