rp2: Fix RP2350 and RP2350B pin alt functions.

RP2350 builds were using the incomplete `rp2_af.csv` alt function table
(originally made for RP2040) which broke pins > 31 in RP2350B (48-pin
QFN-80) builds:

    >>> machine.Pin(31)
    Pin(GPIO31, mode=IN, pull=PULL_DOWN)

    >>> machine.Pin(32)
    Pin(GPIO32, mode=ALT, pull=PULL_DOWN, alt=31)

To fix this, separate alt-functions tables for RP2350 and RP2350B are added
in this commit.

UART_AUX (alt function 11) was also missing, along with XIP_CS1 and
CORESIGHT_TRACE, and they are  now added as well.
