Fix spi_flash_write regression and nvs error recovery
In the previous set of changes related to spi_flash, new alignment checks were added. One of these checks, word alignment of `src` buffer in `nvs_flas_write`, was unnecessary. ROM `SPIWrite` function can handle unaligned source buffers.
This change caused an error to be returned to nvs for some legitimate write operations. Due to a bug in nvs, further write operations were possible, while the internal state of `Page` instance was broken. In WiFi functional tests, this inflicted havoc on the nvs partition, creating multiple duplicate items in the affected page. Because multiple duplicate items per page were never supposed to be handled during page load, duplicates were not removed. Thankfully this caused an assert at a later point in the loading process, otherwise this bug would be very difficult to detect.
This change set fixes the original spi_flash regression, handling of `INVALID` state of `nvs::Page`, and handling of duplicate items.

Feature/tw8155 optimize tx flow control
1. Remove TX flow control in LWIP
2. Make the return value of esp_wifi_internal_tx consistent with LWIP error code
See merge request !164
146f5962 - Make the return value of esp_wifi_internal_tx consistent with LWIP error code so that
the up-layer can detect the out-of-memory error and take action accordingly, such do flow control.
Due to previous flash write bug it was possible to create multiple duplicate entries in a single page.
Recovery logic detected that case and bailed out with an assert.
This change adds graceful recovery from this condition.
Tests included.
lwip: fix tcp rx abnormal issue(tw8242)
In tcp_alloc(), initialize per_soc_tcp_wnd before initializing recv_wnd because recv_wnd depends on per_soc_tcp_wnd.

Currently a restart is required to recover a page from invalid state.
The long-term solution is to detect such a condition and recover automatically (without a restart). This will be implemented in a separate change set.
Previously the test bench would check failure recovery by introducing error after each write operation.
This makes checks a bit more extensive (and much longer) by failing after every word written. Surprisingly, this change didn't expose any bugs.
ROM SPIWrite routine can work with unaligned sources, so this check is unnecessary.
Furthermore, it breaks nvs_set_str and nvs_get_blob when data pointer is unaligned.
Also fix stray backslash in COUNTER_STOP macro
nvs: fix memory leaks in HashList and nvs_close
Fixes TW8162.
Associated test case is run under Instruments on macOS, until I set up valgrind to test this automatically on Linux.

Add cross-core int to accelerate task being awoken from another CPU.
This adds a per-CPU interrupt that can be used to poke the CPU to go do something. In this case all that is implemented is a request to yield the current task, used in case a CPU unblocks a task that runs on another CPU. This gets rid of the limitation that inter-CPU communication using queues, muxes etc can take up to a FreeRTOS tick to happen.
Specs!
Sending an in in a queue of length 1 (essentially a semaphore) as quickly as possible (just a small delay in the sender, to make sure the receiver task gets swapped out) for 10 seconds. Number indicates the amount of ints transferred
Old code:
CPU0->CPU0: 42986
CPU0->CPU1,: 2999
New code:
CPU0->CPU0: 42868
CPU0->CPU1: 62073

Fix the things that broke when adding the new WDTs
Seemingly, I broke a bunch of things when adding the interrupt WDTs and moved the panic handler to the esp32 directory. This fixes that, as well as the issue where flashing would trigger the int wdt. It also bodges in a fix for a merge artifact breaking the halt-on-first-thread-when-openocd-is-connected; that fix should be refined later.

lwip: support max 16 sockets
Since the customers need more sockets in their application, support max 16 sockets,
in other words, the total socket number of UDP/TCP/RAW sockets should not exceed 16.

This implements esp_partition_read, esp_partition_write, esp_partition_erase_range, esp_partition_mmap.
Also removed getters which didn't add much sugar after all.
spi_flash_read and spi_flash_write currently have a limitation that source and destination must be word-aligned.
This can be fixed by adding code paths for various unaligned scenarios, but function signatures also need to be adjusted.
As a first step (since we are pre-1.0 and can still change function signatures) alignment checks are added, and pointer types are relaxed to uint8_t.
Later we will add handling of unaligned operations.
This change also introduces spi_flash_erase_range and spi_flash_get_chip_size functions.
We probably need something like spi_flash_chip_size_detect which will detect actual chip size.
This is to allow single application binary to be used on a variety of boards and modules.
