Allocation of the temporary internal buffer will now repeat until a small enough buffer can be
allocated, and only fail if less than a 256 byte block of internal RAM is free.
Adds unit test for the same, and generic test utility for creating memory pressure.
Previously would try allocate buffer of minimum size 16KB not maximum size 16KB, causing
out of memory errors for any large reads, or if less than 16KB contiguous free heap.
Also, if using legacy API and internal allocation failed then implementation would abort()
instead of returning the error to the caller.
Added test for using large buffers in PSRAM.

Partly revert "efuse: Add support for esp32s2beta"
This partly reverts commit db84ba868c4c7b266f1574a1dc500203630077d8.
Add support for get write protection support, fixed the duplicated
set_write_protection link.
All the write_protection check in the top layer are removed. The lower
levels (chip) should ensure to disable write protection before the
operation start.
