The custom executor feature is now hidden behind the `ExperimentalCustomExecutors` SPI
until it goes through the evolution process.

[BridgeJS] Formalizing ABI Part 1

…#556)

Fix: Ensure BridgeJS.Macros.swift is processed by SwiftToSkeleton

Regenerate BridgeJS files

* Fix missing comma in @_expose attribute for SwiftSyntax602

The SwiftSyntax602 code path in `buildExposeAttributes` was using array
literal syntax to construct `LabeledExprListSyntax`, which doesn't set
`trailingComma` on the AST nodes. This resulted in malformed attributes:
`@_expose(wasm "name")` instead of `@_expose(wasm, "name")`.

The fix uses the result builder syntax with explicit `.with(\.trailingComma,
.commaToken())` to ensure the comma is present in the generated code.

Also adds a dedicated `bridgejs-test` CI job that tests BridgeJS with
multiple Swift/SwiftSyntax version combinations to ensure both code paths
(pre-602 and 602+) are exercised:
- Swift 6.0.3 with SwiftSyntax 600.0.1
- Swift 6.1.2 with SwiftSyntax 601.0.1
- Swift 6.2 with SwiftSyntax 602.0.0

* Rename CI job to test-bridgejs-against-swift-versions

* Simplify CI: let SPM resolve SwiftSyntax version naturally

Remove sed-based version pinning that caused linker errors on Swift 6.2.
Swift 6.2 ships with prebuilt SwiftSyntax 602.0.0, and forcing an exact
version caused duplicate symbol errors during linking.

Each Swift version naturally resolves to compatible SwiftSyntax:
- Swift 6.0.x → SwiftSyntax 600.x
- Swift 6.1.x → SwiftSyntax 601.x
- Swift 6.2.x → SwiftSyntax 602.x

* Remove Swift 6.0.3 from test matrix

The codebase uses trailing commas in argument lists (BridgeJSToolInternal.swift)
which requires Swift 6.1+. Testing with 6.1.2 and 6.2 covers both SwiftSyntax
code paths (non-602 and 602).

* Force SwiftSyntax 602.x for Swift 6.2 CI job

On Swift 6.2, SPM resolves to SwiftSyntax 600.0.1 by default (per Package.swift),
which doesn't have the SwiftSyntax602 module. Use sed to temporarily force
SwiftSyntax 602.x so we actually test the SwiftSyntax602 code path.

This also may avoid the prebuilt binary linker conflicts that occur with
SwiftSyntax 600.0.1 on Swift 6.2.
