ReactNative 0.73 did not include the Hermes WeakMap memory leak fix

[edkimmel]

Description

It looks like ReactNative 0.73 took a build of hermes from September 2023. The WeakMap memory leak was fixed in November. facebook/hermes@e7b2abe

Would it be possible to get a minor version / hotfix built of 0.73 to include that fix? Right now, our choices are to patch and host a custom hermes ourselves or to continue to call GC manually to work around the issue.

Closing as you should ask for this pick here:
reactwg/react-native-releases#98

The change doesn't look that invasive so we should be able to pick it. However we'll need to get a confirmation from @neildhar @tmikov that it's safe to pick this change on for 0.73.
