[JSC] Add parsing for deferred import proposal
https://bugs.webkit.org/show_bug.cgi?id=283133
Reviewed by Yusuke Suzuki.
This patch adds initial parsing support for deferred
imports:
* Adds feature flag for deferred imports
* Adds syntax for `import defer` (no `import.defer` yet)
* Adds parsing tests
* Adds part of data representation for deferred
imports relevant to the parser
* `import defer` acts identical to plain `import` for now
The spec for the proposal is at:
https://github.com/tc39/proposal-defer-import-eval/
* JSTests/stress/modules-syntax-error.js:
* JSTests/stress/modules-syntax-import-defer-error.js: Added.
(shouldThrow):
* JSTests/stress/modules-syntax-import-defer.js: Added.
