6820e0e175 LibWasm: Make sure to place imported functions before the module's 
aafef1e92d broke this while trying to
make the global import available in initialisation, this commit makes
sure we place the module's own functions after all resolved imports.

4fb209d25f LibWasm: Explicitly place the paddings in the WASI API types 
This makes it so we don't rely on e.g. u64 to have an 8-byte alignment,
fixing breakage on i686 systems.

8668851cb1 LibWasm: Do not allow self-referencial globals 
This is written in a somewhat roundabout way in the spec, so the
initial implementation did not implement it correctly.

aff81d318b Everywhere: Run clang-format 
The following command was used to clang-format these files:

    clang-format-16 -i $(find . \
        -not \( -path "./\.*" -prune \) \
        -not \( -path "./Base/*" -prune \) \
        -not \( -path "./Build/*" -prune \) \

        -not \( -path "./Ports/*" -prune \) \
        -type f -name "*.cpp" -o -name "*.h")

538c308357 LibWasm: Stop passing a nonzero 'mode' to open(..., O_DIRECTORY) 
Bionic warns on this, but not passing the mode argument is technically
undefined behaviour (depending on the libc implementation of open), as
our LibC reads `mode` unconditionally (yolo!), just pass a zero to avoid
the UB.

7e6341587b AK+Everywhere: Disallow Error::from_string_view(FooString) 
That pattern seems to show up a lot in code written by people that
aren't intimately familiar with the lifetime model of Error and Strings.
This commit makes the compiler detect it and present a more helpful
diagnostic than "garbage string at runtime".

7e4e9fdb8f LibWasm: Start implementing WASI 
This commit starts adding support for WASI, along with the framework to
implement all the functions (though only a couple are currently
implemented).

This implements the memory object cache and its "reset on grow"
semantics, as the web depends on the exact behaviour.

d5871f5717 AK: Rename Stream::{read,write} to Stream::{read_some,write_some} 
Similar to POSIX read, the basic read and write functions of AK::Stream
do not have a lower limit of how much data they read or write (apart
from "none at all").

Rename the functions to "read some [data]" and "write some [data]" (with
"data" being omitted, since everything here is reading and writing data)
to make them sufficiently distinct from the functions that ensure to
use the entire buffer (which should be the go-to function for most
usages).

No functional changes, just a lot of new FIXMEs.

6b50f23242 LibWasm+LibWeb: Sneak a JS::Completion into Wasm::Result 
Imported functions in Wasm may throw JS exceptions, and we need to
preserve these exceptions so we can pass them to the calling JS code.

This also adds a `assert_wasm_result()` API to Result for cases where
only Wasm traps or values are expected (e.g. internal uses) to avoid
making LibWasm (pointlessly) handle JS exceptions that will never show
up in reality.

8464da1439 AK: Move Stream and SeekableStream from LibCore 
`Stream` will be qualified as `AK::Stream` until we remove the
`Core::Stream` namespace. `IODevice` now reuses the `SeekMode` that is
defined by `SeekableStream`, since defining its own would require us to
qualify it with `AK::SeekMode` everywhere.

9a66a9ac4a LibWasm: Split SaturatingTruncate conversion function by float/non-float 
It's possible to construct a floating point value that when converted to
double is not larger than i64::max(), but when remaining a float is
larger. This patch avoids that edge case with some even less exciting if
constexpr branches to fix a float-cast-overflow UBSAN error on macOS
with llvm 15.0.6.
