* miscellaneous cleanup:
* cleanup some #ifdefs which were slightly hacky when RP2350 was added; use HAS_ flags in preference to PICO_RP2040/RP2350
* make some dependencies more explicit - i.e. compile if the user doesn't want to include certain libraries
* cleanup some directory A -> directory B relative path names in CMakeLists.txt to be SDK root -> directory B
* Update LwIP to 2.2.1
* Update to mbedtls to 3.6.1
* Update lib/cyw43-driver to 1.1.0
* Support using a more recent version of mbedtls
altcp_tls_mbedtls.c is not compatible with mbedtls 3.x so use a
patched version until this is resolved.
* Make sure MBEDTLS_VERSION_MAJOR is visible to LwIP.
* Test mbedtls in kitchen sink
* Add mbedtls to bazel
* Remove btstack Segger RTT from pico-btstack
We now have this in the SDK so adding it again in pico-btstack leads to
link errors.
But it's possible to use the btstack RTT functionality by defining
ENABLE_SEGGER_RTT=1, and if we're not using pico_stio_rtt we still need
to add the btstack RTT source.
* Fix build issues when RTT is enabled
Fixes https://github.com/raspberrypi/pico-examples/issues/565
* Add `pico_btstack_mesh` CMake library to link BlueTooth Mesh capabilities hidden in BTstack
* Add pico_btstack_mesh to docs

* fix feature request #1442
* Do not require -I before each addtional path
* Fix pico_btstack_make_gatt_header warning
gatt header files are always made into the "generated" folder so you get
a warning if you have more than one target generating a gatt header with
the same name.
Also, simplify the expansion of ARGN
* Improve pico_btstack_make_gatt_header description

* Add new pico_flash library, with flash_safe_execute(func) method to help with preventing IRQs and other core accessing flash with pico_multicore or FreeRTOS SMP
If you just want to link to pico_btstack_flash_bank_headers to include
the header file you also have to link to pico_btstack_base_headers.
ENABLE_CLASSIC and ENABLE_BLE are used in header files so should be
added by the headers library
Fixes#1271
