internal/wasi: update to [email protected]

[ydnar]

This updates the "vendor" submodule of wasm-tools-go and regenerates the WASI 0.2 bindings with the most recent version of wit-bindgen-go. Full release notes on the changes:

v0.1.2 — 2024-07-05

Added

• Canonical ABI lifting code for flags and variant types.
• Lifting code for result and variant will now panic if caller passes an invalid case.
• Additional test coverage for variant and flags cases.

Removed

• Package cm: Removed unused functions Reinterpret2, LowerResult, LowerBool, BoolToU64, S64ToF64.
• Package cm: Removed unused experimental flags implementation behind a build tag.

Fixed

• Lifting code for result with no error type will now correctly set IsErr.

v0.1.1 — 2024-07-04

This release changes the memory layout of variant and result types to permit passing these types on the stack safely. This required breaking changes to package cm, detailed below, as well as slightly more verbose type signatures for WIT functions that return a typed result.

Breaking Changes

• Type cm.Result is now cm.BoolResult.
• Types cm.OKResult and cm.ErrResult have been removed, replaced with a more generalized cm.Result[Shape, OK, Err] type.

Added

• WIT labels with uppercase acronyms or initialisms are now preserved in Go form. For example, the WIT name time-EOD will result in the Go name TimeEOD.
• OK is now a predefined initialism. For example, the WIT name state-ok would previously translate into the Go name StateOk instead of the idiomatic StateOK.

Fixed

• #95: wit-bindgen-go now correctly generates packed data shape types for variant and result types.
• Fixed swapped Shape and Align type parameters in the functions cm.New and cm.Case for manipulating variant types.
• Variant validation now correctly reports variant instead of result in panic messages.

Do any of these changes require updates to the libc_wasip2 wrappers?

[ydnar]

None AFAIK.
