Update the PewPew M4 board and circuitpython-stage

[deshipu]

PewPew M4 now has the pew.py added to its frozen libraries. Some
features needed to be disabled to make room for that.

@deshipu Note that it is now a lot easier to adjust the size of the internal filesystem, the size of the nvm area, etc.

Oh, really? Is there documentation on that?

It was part of #2371. See

circuitpython/ports/atmel-samd/mpconfigport.h

Lines 116 to 135 in 32b8203

	#ifdef SAMD51
	#ifndef CIRCUITPY_INTERNAL_NVM_SIZE
	#define CIRCUITPY_INTERNAL_NVM_SIZE (8192)
	#endif
	#ifndef CIRCUITPY_DEFAULT_STACK_SIZE
	#define CIRCUITPY_DEFAULT_STACK_SIZE (24*1024)
	#endif
	// If CIRCUITPY is internal, use half of flash for it.
	#if INTERNAL_FLASH_FILESYSTEM
	#ifndef CIRCUITPY_INTERNAL_FLASH_FILESYSTEM_SIZE
	#define CIRCUITPY_INTERNAL_FLASH_FILESYSTEM_SIZE (FLASH_SIZE/2)
	#endif
	#else
	#define CIRCUITPY_INTERNAL_FLASH_FILESYSTEM_SIZE (0)
	#endif
	#endif // SAMD51

, for SAMD51. So you can change these constants in your mpconfigboard.h. Note that changing the NVM size will move the filesystem, so the existing filesystem in internal flash will get trashed.
