shared/tinyusb: Revert setting of CFG_TUD_CDC_EP_BUFSIZE to 256.

Browse Source 
This reverts commit 0613d3e3561a82fffa36594647ef916b19bc912b.

The value of CFG_TUD_CDC_EP_BUFSIZE should match the endpoint size,
otherwise data may stay in the lower layers of the USB stack (and not
passed up to the higher layers) until a total of CFG_TUD_CDC_EP_BUFSIZE
bytes have been received, which may not happen for a long time.

Fixes issue #11253.
