provider/cloudflare: Change cloudflare_record type to ForceNew

[stack72]

The CloudFlare API does not allow types to be changed (i.e. A to CNAME)
after creation

Fixes #5316

make testacc TEST=./builtin/providers/cloudflare TESTARGS='-run=TestAccCLOudflareRecord'
==> Checking that code complies with gofmt requirements...
go generate $(go list ./... | grep -v /vendor/)
TF_ACC=1 go test ./builtin/providers/cloudflare -v -run=TestAccCLOudflareRecord -timeout 120m
=== RUN   TestAccCLOudflareRecord_Basic
--- PASS: TestAccCLOudflareRecord_Basic (5.61s)
=== RUN   TestAccCLOudflareRecord_Updated
--- PASS: TestAccCLOudflareRecord_Updated (9.08s)
=== RUN   TestAccCLOudflareRecord_forceNewRecord
--- PASS: TestAccCLOudflareRecord_forceNewRecord (9.87s)
PASS
