Add setting to configure the max memory for tsserver

[MLoughry]

This PR fixes #33524 by adding a setting typescript.tsserver.maxTsServerMemory, which passes the setting on to tsserver using --max-old-space-size

Thanks @MLoughry! Just want to confirm, using a high memory setting does fix the out of memory issues for you?

[MLoughry]

@mjbvz Yes. tsserver still takes a while to spin up on our massive project, but it no longer crashes and "forgets" all the work it did when I configure a higher memory limit.

Thanks!
