54419e870d xtensa/esp32s3: Implement per-process address environments.
Give the ESP32-S3 the arch_addrenv_t machinery that BUILD_KERNEL needs:  a
per-process page directory built from the 64 KiB MMU pages of the chip, with
allocation, teardown, and the vaddr-to-paddr translation that the kernel uses
to reach a user buffer.

The MMU, PMS and WCL primitives are exposed as an arch API first, because the
address environment code and the protected user split both need them and
neither owns them.

3acdbef60d xtensa:arch: force up_getsp to inline
Up_getsp may be not inline in gcc, thus get the sp
is up_getsp function's sp, not the caller function.
