This is an automated change with the following commands:

* Add missing `load()` statements for things provided by @rules_cc. This
is required for Bazel >9.
* Sort attributes on build targets.
* Add missing trailing commas where applicable.
* [Bazel] Fix bazel build, add presubmit
* Fixes a missing dep in the Bazel build breaking the host build.
* Automagically finds all board headers.
* Improves presubmit script polish for GH Action readiness.
* Adds a GitHub action workflow for the Bazel build.
* Disable failing checks
* Disables Windows, as there's a mix of real build errors and
overly-ambitious checks that don't work on Windows.
* Disables extra checks temporarily since it's currently failing.
* Add host Bazel build
Updates target_compatible_with across the repo to ensure that wildcard
builds for both host and rp2040 succeed.
* Get unit tests building
* Add Python script to identify build system differences
Uses the build system tags to make it easier to identify differences
between the CMake and Bazel builds.
* Temporarily disable pico divider test
* Support PICO_BARE_METAL in Bazel
* Support PICO_NO_GC_SECTIONS in Bazel
* Support boot2 configuration in Bazel
Adds support for PICO_DEFAULT_BOOT_STAGE2 and
PICO_DEFAULT_BOOT_STAGE2_FILE in the Bazel build.
* Allowlist some CMake-only options
* Support CXX configuration options in Bazel
* Move multiple_choice_flag.bzl
* Support all pico boards
* Support linking multiple stdio implementations
Changes the Bazel build so stdio implementations are no longer mutually
exclusive.
* Add PICO_BOOT_STAGE2_LINK_IMAGE
* Support PICO_CMSIS_PATH in Bazel
* Support PICO_USE_DEFAULT_MAX_PAGE_SIZE in Bazel
* Silence PICO_CMSIS_VENDOR and PICO_CMSIS_DEVICE differences
* Support PICO_STDIO_USB_CONNECT_WAIT_TIMEOUT_MS in Bazel
* Properly support version defines
* Support embedding binary info in Bazel
* Embed build type in binary
* Support different linker scripts in Bazel build
* Finish out missing PICO_BUILD_DEFINE in Bazel build
* Support PICO_NO_TARGET_NAME
* Reorganize initial configuration options in Bazel
Cleans up and reorganizes some of the initial configuration options
added to the Bazel build so everything is consistent.
* Add builds for pioasm and elf2uf2
* Use Python rules from rules_python
* Actually link in output formats in pioasm tool
* Make tools have public visibility
* Add UF2 Bazel aspect
* Add TODOs for pioasm/uf2 helpers
* Fix compile flag typo
* Update Bazel SDK configuration strings to match recent CMake changes
* Fix pico_divider test
* Clean up straggling TODOs
* Clarify pico_stdio_test compatibility
* Initial Bazel Pico W support
* Add new files from develop
* Clean up compatibility expressions in Bazel build
* Clean up rp2 constraint handling in Bazel
* More Bazel docs cleanup
* Format Bazel build files
* Consolidate transitions in the Pico SDK
* Make every _allowlist_function_transition explicit
* More docs cleanup
* Add a few missing defines
* Improve PICO_CONFIG_HEADER correctness in Bazel
* Minor docs clarifications
1. Make sure Pico SDK libraries have the correct dependencies on other SDK libraries
2. Pico SDK libraries all have _headers variants to include the headers. This may facilitate building user STATIC libraries without
pulling in SDK code, though care will still need to be taken w.r.t. values of #defines
3. Make sure the _headers versions also have the correct dependencies
Note: There are a few exceptions to 1. for some non code libraries like pico_standard_link and pico_cxx_options
* Extract all poll/threadsafe_background/freertos from cyw43_arch into new abstraction async_context:
* provides support for asynchronous events (timers/IRQ notifications) to be handled in a safe context.
* now guarantees all callbacks happen on a single core.
* is reusable by multiple different libraries (stdio_usb can now be ported to this but hasn't been yet).
* supports multiple independent instances (independent instances will not block each other).
* cyw43_arch libraries cleaned up to use the new abstraction. Note each distinct cyw43_arch type is now a very thin layer that creates the right type of context and adds cyw43_driver and lwip support as appropriate.
Additionally,
* Add new pico_time and hardware_alarm APIs
* Add from_us_since_boot()
* Add alarm_pool_create_with_unused_hardware_alarm()
* Add alarm_pool_add_alarm_at_force_in_context()
* Add hardware_alarm_claim_unused()
* Add hardware_alarm_force_irq()
* Added panic_compact() and some minor comment cleanup; moved FIRST_USER_IRQ define to platform_defs.h
