Merge bitcoin/bitcoin#32023: wallet: removed duplicate call to GetDescriptorScriptPubKeyMan

Browse Source 
55b931934a removed duplicate calling of GetDescriptorScriptPubKeyMan (Saikiran)

Pull request description:

  Removed duplicate call to GetDescriptorScriptPubKeyMan and
  Instead of checking linearly I have used find method so time complexity reduced significantly for GetDescriptorScriptPubKeyMan
  after this fix improved performance of importdescriptor part refs https://github.com/bitcoin/bitcoin/issues/32013.

  **Steps to reproduce in testnet environment**

  **Input size:** 2 million address in the wallet

  **Step1:** call importaddresdescriptor rpc method
  observe the time it has taken.

  **With the provided fix:**
  Do the same steps again
  observe the time it has taken.

  There is a huge improvement in the performance. (previously it may take 5 to 6 seconds now it will take 1 seconds or less)

  main changes i've made during this pr:

  1. remove duplicate call to GetDescriptorScriptPubKeyMan method
  2. And inside GetDescriptorScriptPubKeyMan method previously we checking **each address linearly** so each time it is calling HasWallet method which has aquired lock.
  3. Now i've modified this logic call **find method on the map (O(logn)**) time it is taking, so only once we calling HasWallet method.

  **Note:** Smaller inputs in the wallet you may not see the issue but huge wallet size it will definitely impact the performance.
