pkg/tinyusb: fix default VID/PID configuration #19377

Contribution description

This PR fixes the default VID/PID configuration if tinyUSB board reset feature is used.

While reviewing PR #19086 I was wondering why esp32s2-wemos-mini requires to set USB_VID/USB_PID explicitly to USB_VID_TESTING/USB_PID_TESTING. The reason was that tinyUSB board reset feature wasn't declared as RIOT internal.

Testing procedure

Flashing esp32s2-wemos-mini should still work.

BOARD=esp32s2-wemos-mini make -C tests/shell flash

The VID/PID should be 1209:7d00 and not 1209:7d01.

Issues/PRs references

Defining the feature as RIOT internal avoids that the board has to set USB_VID and USB_PID explicit to USB_VID_TESTInG/USB_PID_TESTING if tinyUSB board reset feature is used.

19371: sys/usbus: check for the number of required and provided EPs in static configurations r=benpicco a=gschorcht

### Contribution description

This PR provides a static check at compile time whether the number of EPs required in a static configuration does not exceed the number of EPs provided by the USB device.

#### Background

In issue #19359 the problem was reported that `usbus_cdc_ecm` didn't work together with `stdio_cdc_acm` on some STM32 boards. The reason for some of the boards was simply that the application tried to allocate more EPs than available and simply ignored this and just didn't work.

#### Solution

Since `auto_init_usb` uses a static configuration with exactly one USBUS stack instance and one USB device, at least in case `auto_init` is used a static check can be carried out to make sure that the number of EPs required by the application doesn't exceed the number of EPs provided by the USB device. For this purpose, each `usbus_*` module defines the number of IN and OUT EPs required by that module. Each USB device driver defines the number of EPs provided by USB device if it differs from the default of 8 EPs. During the auto initialization the total number of required IN and OUT EPs is then compared with the number of EPs provided by the USB device using a static assert.

### Testing procedure

1. Green CI
2. Compilation of
   ```python
   USEMODULE='stdio_cdc_acm' BOARD=nucleo-f439zi make -j8 -C tests/usbus_cdc_ecm
   ```
   should lead to compilation error
   ```python
   sys/auto_init/usb/auto_init_usb.c:81:1: error: static assertion failed: "Number of required IN endpoints exceeded"
    _Static_assert(USBUS_EP_IN_REQUIRED_NUMOF <= USBDEV_NUM_ENDPOINTS,
    ^~~~~~~~~~~~~~
   Makefile.base:146: recipe for target 'tests/usbus_cdc_ecm/bin/nucleo-f439zi/auto_init_usbus/auto_init_usb.o' failed
   ```
   while compilation of
   ```
   USEMODULE='stdio_cdc_acm' BOARD=nucleo-f767zi make -j8 -C tests/usbus_cdc_ecm
   ```
   should work.

19374: makefiles/boards/stm32: fix DFU_USB_ID handling r=benpicco a=gschorcht

### Contribution description

This PR fixes the still existing problem that an application can't be flashed to a STM32 board if it uses `riotboot_dfu` with default  VID/PID (1209:7d02).

In PR #18964 item 1, the problem was already described that an application can't be flashed on a board that is using `riotboot_dfu`. Using for example
```python
FEATURES_REQUIRED+=riotboot USEMODULE+=usbus_dfu make -C examples/saul BOARD=nucleo-f767zi \
PROGRAMMER=dfu-util all riotboot/flash-slot0
```
always leads to error
```python
/home/gs/src/RIOT-Xtensa-ESP.esp-idf-4.4/makefiles/boards/stm32.inc.mk:28: *** DFU_USB_ID is not set.  Stop.
/home/gs/src/RIOT-Xtensa-ESP.esp-idf-4.4/makefiles/boot/riotboot.mk:87: recipe for target 'riotboot/bootloader/binfile' failed
```
even if `DFU_USB_ID` variable is set as described in documentation.
```python
FEATURES_REQUIRED+=riotboot USEMODULE+=usbus_dfu make -C examples/saul BOARD=nucleo-f767zi \
PROGRAMMER=dfu-util DFU_USB_ID=1209:7d02 all riotboot/flash-slot0
```
The reason is that the variable `DFU_USB_ID` isn't exported and the check https://github.com/RIOT-OS/RIOT/blob/8dc8bf35678493ecc8ef110e2f0359a67c03894c/makefiles/boards/stm32.inc.mk#L27-L29 sees an empty `DFU_USB_ID` variable here. It prevents to use `dfu-util` event though the following `dfu-util.mk` will generate a default value for this variable from the `USB_VID` and `USB_PID` variables if necessary.

Commit 6a76b94 of PR #18964 tried to fix this problem but wasn't merged for any reason.

To fix this problem, the check is completely removed. If a board such as `weact-f4x1cx` uses a DFU boorloader and requires a certain VID/PID combination, board's makefile is responsible to set `DFU_USB_ID` variable.

### Testing procedure

It is not necessary to use a real boad, checking the compilation process is sufficient.

1. Using default VID/PID as described in documentation:
   ```python
   FEATURES_REQUIRED+=riotboot USEMODULE+=usbus_dfu make -C examples/saul BOARD=nucleo-f767zi \
   PROGRAMMER=dfu-util all riotboot/flash-slot0
   ```
   can't be compiled without this PR but calls `dfu-util` correctly with this PR using the default VID/PID:
   ```python
   dfu-util --device 1209:7d02 --alt 0 --download examples/saul/bin/nucleo-f767zi/riotboot_files/slot0.1678440536.bin
   ```
2. Using a VID/PID as described in documentation:
   ```python
   FEATURES_REQUIRED+=riotboot USEMODULE+=usbus_dfu make -C examples/saul BOARD=nucleo-f767zi \
   DFU_USB_ID=1209:affe PROGRAMMER=dfu-util all riotboot/flash-slot0
   ```
   can't be compiled without this PR but calls `dfu-util` correctly with this PR using the default VID/PID:
   ```python
   dfu-util --device 1209:affe --alt 0 --download examples/saul/bin/nucleo-f767zi/riotboot_files/slot0.1678440536.bin
   ```
3. Compiling a board with DFU bootloader
   ```python
   make -C examples/saul flash BOARD=weact-f411ce
   ```
   should still call dfu-util with correct VID/PID:
   ```python
   dfu-util --device 0483:df11 --alt 0 --download /home/gs/src/RIOT-Xtensa-ESP.esp-idf-4.4/examples/saul/bin/weact-f411ce/saul_example.bin  --dfuse-address 0x8000000:leave
   ```
