Enable HAVE_LCD_FLIP for the Clip Zip and implement lcd_set_flip()
in the LCD driver, making the Display -> Flip Display setting work.
This lets the player be used upside down, e.g. clipped to clothing
with the control buttons pointing up and screen on the bottom.
Defining HAVE_LCD_FLIP also activates the existing button remap in
button_flip() (firmware/drivers/button.c) for this target: while the
display is flipped, LEFT/RIGHT, UP/DOWN and the volume keys are all
swapped to match the new orientation, so the whole device is usable
upside down, not just readable.
The flip is done in hardware by reversing the controller's GRAM write
direction and mirroring the write window in lcd_setup_rect, so partial
updates keep working and there is no per-frame cost. Both panel
variants are handled: the type 0 WiseChip/SEPS114A via MEMORY_WRITE/READ
(1Dh, 0x02), and the type 1 Visionox/LD7134 via the Graphic RAM Writing
Direction register (05h, 0x03). The direction register is written in
lcd_enable(), so it is set while the panel is powered and is re-applied
after display standby; lcd_set_flip() cycles the panel off and on so a
change to the setting takes effect immediately.
For the simulator, which has no real LCD controller, lcd_set_flip() is
implemented in the SDL LCD driver (lcd-bitmap.c) as a software mirror of
the framebuffer, so the flip is visible in theme previews; the generic
uisimulator stub is guarded out when HAVE_LCD_FLIP is defined.
Tested on real type 1 / LD7134 hardware in both orientations: display
content, button remapping and album art are all correct, and test_fps
shows partial updates run at full speed when flipped (1/4 frame 325 fps,
matching the non-flipped rate). The type 0 / SEPS114A path uses the same
approach; the 0x02 direction value was confirmed to flip a type 0 panel
by William Wilgus during review.

this commit is a combination of the following changes, which
significantly refactors usb core and class drivers.
1. unify usb buffers of each class driver to reduce iram usage
currently, many class drivers allocate their own buffer to receive
control out data, which is a waste of iram.
share one common buffer for that usage to address the issue.
2. simplify control request handling by implicitly receiving write
request data packets
change 1 above fixed the data destination. therefore, having the core
receive the data allows us to reduce the class driver's work and
simplifies the api.
3. enhance usb core's control request handling and unify the legacy
driver api
in order to implement change 2, both the legacy and new driver apis
should be supported. so that, using the designware driver as a
reference, the new driver api functionality is move into usb core.
this simplifies the usb device drivers by requiring them to implement
only the functionalities equivalent to the legacy api.

the capabilities of endpoint of several devices such as dwc2 change during
runtime, so they cannot be determined during driver initialization.
therefore, allocation using ep_specs is inappropriate.
to support these devices, add functions to the driver that determine whether
endpoints are available and make allocation more flexible.
