lib: drop unused or duplicate curlx/timeval.h includes

Note: This patch doesn't aim to add `timeval.h` includes missing from
local headers using `curltime` type. They remain relying on `urldata.h`
being included first. This patch also doesn't delete existing, used
includes already present in local headers (as internal users may rely
on them).

Ref: #20106
Closes #20126
