The UDC driver for this beautiful USB controller is mostly rewritten
from scratch. USB Pad Calibration and clock handling are copied from the
usb_dc_sam0 driver.
The driver uses multipacket transfers for all endpoints except the OUT
control endpoint. The OUT control endpoint has a buffer that is always
mapped to the endpoint buffer register so that it always has a valid
buffer. The driver provides up to 7 IN and 7 OUT endpoints that support
any type of transfer. Double buffering is not used, for the possible
case of isochronous transfers some changes would be required in the
future.

In my opinion, the user is supposed to configure the speed of the stack
and drivers ough to honor that choice. However current Zephyr USB
maintainer imposes that the dependency is the other way round, i.e.
that user first needs to disable High-Speed chirp at driver level and
only then can select Full-Speed only operation. Adhere to the
arbitrarily set up rule to allow this really necessary functionality to
enter Zephyr.
I consider this change to be harmful because it opens up a Kconfig trap
that allows configuring High-Speed capable stack with a device driver
limited to Full-Speed only operation.

Two main ideas behind setting maximum speed are:
* Allow code and RAM optimizations at compile time
* Allow High-Speed capable drivers to limit operating speed to user
choice.
This commit only introduces the necessary Kconfig options but does not
implement any code or RAM optimizations and does not modify any driver.

This driver is mostly rewritten from scratch, with some parts borrowed
from the usb_dc_rpi_pico driver implemented by Pete Johanson.
This driver does not use any function from RPI PICO HAL and actually
could be furter improved to not use any defines or types from the HAL as
they are confusing and overdo it with volatile qualifiers.

Introduce UDC_BUF_POOL_*_DEFINE macros based on NET_BUF_POOL_*_DEFINE
macros but use our own version of alloc and unref callbacks to get
buffers with specific alignment and granularity. Also, do not use ref
callback because it breaks alignment.
Also introduces helper macros for defining and checking UDC
driver-compliant static buffers.

udc_mcux_ehci is based on the MCUX USB controller driver
(usb_device_ehci.c); udc_mcux_ip3511 is based on the
MCUX USB controller driver (usb_device_lpcip3511.c);
add related Kconfig and CMake; include the usb_phy.h path in
modules/hal_nxp/usb/CMakeLists.txt because udc_mcux.c use it;
add related macros to usb_device_config.h;
update CMakeLists for udc_mcux_ehci and udc_mcux_ip3511.

The driver currently supports only dedicated FIFO mode (with
dynfifosizing if enabled). Control, bulk and interrupt transfers are
supported, isochronous transfers are not yet supported. The driver
accesses controller registers using sys_io.h, but for debugging purposes
one can get a register map from the driver's config, similar to the
usb_dc_dw.c driver.
Initial support also has vendor quirks for the STM32F4 SoC family.
Tested on NUCLEO-F413HG.

Add UDC driver for STM32 based MCU, relying on HAL/PCD.
This has been tested with cdc_acm sample on the following boards:
- 96b_carbon (STM32F4)
- disco_l475_iot1 (STM32L4)
- nucleo_wb55rg (STM32WB)
- nucleo_h723zg (STM32H7)
- stm32f3_disco (STM32F3)
This fails at runtime for the following:
- b_u585i_iot2a (STM32U5)

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.
