Merge bitcoin/bitcoin#28540: tests: Fix wallet_resendwallettransactions.py intermittent failure by using manual bumps instead of bumpfee

b5a962564eb15075e4e2a7bc0c235a56fa998ac3 tests: Use manual bumps instead of bumpfee for resendwallettransactions (Andrew Chow)

Pull request description:

  Bumpfee will try to increase the entire package to the target feerate, which causes repeated bumpfees to quickly shoot up in fees, causing intermittent failures when the fee is too large. We don't care about this property, just that the child is continuously replaced until we observe it's position in mapWallet is before its parent. Instead of using bumpfee, we can create raw transactions which have only pay (just above) the additional incremental relay fee, thus avoiding this problem.

  Fixes #28491

    ACK b5a962564eb15075e4e2a7bc0c235a56fa998ac3 -> adding the `try_rpc` to avoid (skip) any possible failure around the manual bump fee (if we ever reach it as [explained](https://github.com/bitcoin/bitcoin/pull/28540#issuecomment-1737648048)) makes a lot of sense as the spirit of the test is the tx (child before parent) sort in the `mapWallet` (as also [explained](https://github.com/bitcoin/bitcoin/issues/28491#issuecomment-1736161363)).
