[WebAssembly] Add -wasm-use-legacy-eh option (#122158)
This replaces the existing `-wasm-enable-exnref` with `-wasm-use-legacy-eh` option, in an effort to make the new standardized exnref proposal the 'default' state and the legacy proposal needs to be separately enabled an option. But given that most users haven't switched to the new proposal and major web browsers haven't turned it on by default, this `-wasm-use-legacy-eh` is turned on by default, so nothing will change for now for the functionality perspective. This also removes the restriction that `-wasm-enable-exnref` be only used with `-wasm-enable-eh` because this option is enabled by default. This option does not have any effect when `-wasm-enable-eh` is not used.

* Support for the new standardized [Exception Handling] proposal is added.
254+
The [legacy Exception Handling] proposal is still supported, and turned on by
255+
the newly added `-wasm-use-legacy-eh` option. Given that major web browsers
256+
still default to the legacy EH proposal, this option is turned on by default
257+
for the moment.
