Remove deprecated treasury pallet calls (paritytech#3820)

# ISSUE
- Link to the issue:
paritytech#3800
# Deliverables
- [x] remove deprecated calls;
(paritytech@d579b67)
- [x] set explicit coded indexes for Error and Event enums, remove
unused variants and keep the same indexes for the rest;
(paritytech@d579b67)
- [x] remove unused Config's type parameters;
(paritytech@d579b67)
- [x] remove irrelevant tests and adopt relevant using old api;
(paritytech@d579b67)
- [x] remove benchmarks for removed calls;
(paritytech@1a3d5f1)
- [x] prdoc
(paritytech@d579b67)
- [x] remove deprecated methods from the `treasury/README.md` and add
up-to-date dispatchable functions documentation
(paritytech@d579b67)
- [x] remove deprecated weight functions
(paritytech@8f74134)
> ### Separated to other issues
> - [ ] remove storage items like Proposals and ProposalCount, that are
not used anymore

Adjust all treasury pallet instances within polkadot-sdk
- [x] `pallet_bounty`, `tip`, `child_bounties`:
openguild-labs#3
- [x] Remove deprecated treasury weight functions used in Westend and
Rococo runtime `collective-westend`, `collective-rococo`

Add migration for westend and rococo to clean the data from removed
storage items
- [ ] paritytech#3828

+
+doc:
+  - audience: Runtime User
+    description: |
+      This PR remove deprecated calls, relevant tests from `pallet-treasury`.
+      - Remove deprecated calls `propose_spend`, `reject_proposal`, `approve_proposal`.
+      - Replace the code flow of `propose_spend` then `approve_proposal` with `spend_local`
+      - Remove deprecated calls' related weight functions and test cases.
+      - Remove deprecated parameter types: ProposalBond, ProposalBondMaximum, ProposalBondMinimum
+      - Remove pallet treasury's relevant deprecated code in pallet-tips, pallet-bounties and pallet-child-bounties
