tests: don't mutate global structs in core scheduler tests (#16120)
Some of the core scheduler tests need the maximum batch size for writes to be
smaller than the usual `structs.MaxUUIDsPerWriteRequest`. But they do so by
unsafely modifying the global struct, which creates test flakes in other tests.

Modify the functions under test to take a batch size parameter. Production code
will pass the global while the tests can inject smaller values. Turn the
`structs.MaxUUIDsPerWriteRequest` into a constant, and add a semgrep rule for
avoiding this kind of thing in the future.

// MaxUUIDsPerWriteRequest is the maximum number of UUIDs that can be included
// within a single write request. This is to ensure that the Raft message does
// not become too large. The resulting value corresponds to 0.25MB of IDs or
// 7281 UUID strings.
const MaxUUIDsPerWriteRequest = 7281 // (1024 * 256) / 36
