Create a wasm-tools specific module that can require go1.22 for wasm-tools-go.
Wasm linear memory is always initialized to zero by definition,
so there's no need to waste time zeroing out this allocation. This
is the case for freshly-obtained memory from mmap().

The os package isn't particularly useful on wasm-unknown, but just like
on baremetal systems it's imported by a lot of packages so it should at
least be possible to import this package.
The encoding/binary package in Go 1.23 imports the slices package, which
results in circular import when imported from the machine package.
Therefore, encoding/binary cannot be used in the machine package.
This commit fixes that by introducing a new internal/binary package that
is just plain Go code without dependencies. It can be safely used
anywhere (including the runtime if needed).
The machine package wasn't tested for every board. Therefore, add a new
serial-like test that also tries to import the machine package. This
should highlight potential issues in the future.
- Add ReadRegister and WriteRegister (because they're still used by
some packages).
- Fix out-of-bounds panic in I2C.Tx when either w or r has a length of
zero (or is nil).
sleepTicks calls machineLightSleep with the duration cast to an unsigned
integer. This underflow for negative durations.

* lint: expand to src/{os,reflect}, fix or suppress what it found
* internal/tools/tools.go: the tools idiom requires a build tag guard to avoid go test complaints
This is much, _much_ faster than __tinygo_spi_transfer which can only
transfer a single byte at a time. This is especially important for
simulated displays.
I've already implemented the browser side of this on the playground and
have used this patch for local testing where it massively speeds up
display operations.
This makes all rp2040 boards available for simulation using
-tags=<board_name>. Importantly, this includes the Gopher Badge which
I'm working on to add to the TinyGo Playground.
This is makes it easier to use these in simulation, plus it avoids
duplication. The only downside I see is that more UARTs get defined than
a board supports, but no existing code should break (no UARTs get
renamed for example).
This eliminates the 'wasi' build tag in favor of 'GOOS=wasip1', introduced in Go 1.21.
For backwards compatablity, -target=wasi is a synonym for -target=wasip1.
Support for `-panic=trap` was previously a pass in the optimization
pipeline. This change moves it to the compiler and runtime, which in my
opinion is a much better place.
As a side effect, it also fixes
https://github.com/tinygo-org/tinygo/issues/4161 by trapping inside
runtime.runtimePanicAt and not just runtime.runtimePanic.
This change also adds a test for the list of imported functions. This is
a more generic test where it's easy to add more tests for WebAssembly
file properties, such as exported functions.
This updates lib/cmsis-svd, pulling in the updates to the Espressif SVD
files here:
https://github.com/cmsis-svd/cmsis-svd-data/pull/3
This is needed for wifi/BLE support on the ESP32-C3 (the older SVD files
were missing some necessary interrupts).
