[jdk17u-dev] RFR: 8294591: Fix cast-function-type warning in TemplateTable

[Aleksey Shipilev]

Need this to unblock MacOS compiler update in GHA.

Partially backports original https://github.com/openjdk/jdk/commit/fc616588c1bf731150a9d9b80033bb589bcb231f. There is a conflict, because the original [JDK-8294314](https://bugs.openjdk.org/browse/JDK-8294314) that added more verbose build warnings is not in 17u-dev yet. If we backport that one later, we can remove the warning blocks related to these files.

Additional testing:
 - [x] Linux AArch64 server fastdebug, `all`
 - [x] Linux x86_64 server fastdebug, `all`
