fix: remove -Wextra-semi

[getchoo]

Parent PR: #1107

this flag is unavailable on gcc versions < 8. we could detect the
version of the compiler here, but i don't think we lose much in this
flags removal and this is a simpler option

Can we close this in favor of this commit:edd1b08 ?
From my understanding, this only happens with the gnu compiler.

i would be up for that, but i can't confirm whether or not the flag has always been in clang - or at the very least, has been in all decently modern versions. a bit of googling gave me references to the flag around clang 7/8 (which aren't that old), but i can't find anything earlier. this might just be the safest option unless we dig up some random patch note to date the flag in clang

Dug out the past: llvm/llvm-project@2f7dc46
It looks like this option was added in Clang 3.2(https://github.com/llvm/llvm-project/releases/tag/llvmorg-3.2.0-rc1)
Sadly no direct mention in the release notes of the flag was found, just the random patch that adds it.
