feat(operations-gen): add deploy_contract_types for same-ABI multi-label deploy (#1056)

Currently operations-gen does not support generating operation with the
same contract byte code but each with different contract types (MCMS
setup - proposer,canceller,bypasser).

Adds a new `deploy_contract_types` field to the EVM contract config that
allows a single contract entry to register multiple ContractType labels
(e.g. ProposerManyChainMultiSig, BypasserManyChainMultiSig,
CancellerManyChainMultiSig) in the generated BytecodeByTypeAndVersion
map.


```yaml
version: "1.0.0"
chain_family: evm
input:
  gobindings_package: "github.com/smartcontractkit/chainlink-deployments-framework/tools/operations-gen/testdata/evm/gobindings"
  zksync_bindings_package: "github.com/smartcontractkit/chainlink-deployments-framework/tools/operations-gen/testdata/evm/zksync_bindings"
output:
  base_path: "."
contracts:
  - contract_name: ManyChainMultiSig
    version: "1.0.0"
    package_name: many_chain_multi_sig
    zksync_bytecode: ManyChainMultiSigZkBytecode
    deploy_contract_types:
      - ProposerManyChainMultiSig
      - BypasserManyChainMultiSig
      - CancellerManyChainMultiSig
    functions:
      - name: owner
        access: public
```

will generate 
```go
...
var ProposerManyChainMultiSigContractType cldf_deployment.ContractType = "ProposerManyChainMultiSig"
var ProposerManyChainMultiSigTypeAndVersion = cldf_deployment.NewTypeAndVersion(ProposerManyChainMultiSigContractType, *Version)
var BypasserManyChainMultiSigContractType cldf_deployment.ContractType = "BypasserManyChainMultiSig"
var BypasserManyChainMultiSigTypeAndVersion = cldf_deployment.NewTypeAndVersion(BypasserManyChainMultiSigContractType, *Version)
var CancellerManyChainMultiSigContractType cldf_deployment.ContractType = "CancellerManyChainMultiSig"
var CancellerManyChainMultiSigTypeAndVersion = cldf_deployment.NewTypeAndVersion(CancellerManyChainMultiSigContractType, *Version)

var Deploy = contract.NewDeploy(contract.DeployParams[ConstructorArgs]{
	Name:             "many-chain-multi-sig:deploy",
	Version:          Version,
	Description:      "Deploys the ManyChainMultiSig contract",
	ContractMetadata: gobindings.ManyChainMultiSigMetaData,
	BytecodeByTypeAndVersion: map[string]contract.Bytecode{

			EVM:      common.FromHex(gobindings.ManyChainMultiSigMetaData.Bin),

			EVM:      common.FromHex(gobindings.ManyChainMultiSigMetaData.Bin),

+## Deploy contract types
+
+Some contracts are deployed multiple times with different semantic roles, each requiring a distinct
+`ContractType` label in the datastore (e.g. `ProposerManyChainMultiSig`, `BypasserManyChainMultiSig`,
+`CancellerManyChainMultiSig`). Because all three share the same ABI and bytecode, using three
+separate YAML contract entries would generate three near-identical files. `deploy_contract_types`
+solves this: one entry, one generated package, one `Deploy` var — but the `BytecodeByTypeAndVersion`
+map holds a key for every label so the caller can deploy under whichever type it needs.
+
+```yaml
+- contract_name: ManyChainMultiSig
+  version: "1.0.0"
+  deploy_contract_types:
+    - ProposerManyChainMultiSig
+    - BypasserManyChainMultiSig
+    - CancellerManyChainMultiSig
+  functions:
+    - name: setConfig
+      access: owner
+```
+
+This generates:
+
+```go
+var ContractType cldf_deployment.ContractType = "ManyChainMultiSig"
+var ProposerManyChainMultiSigContractType cldf_deployment.ContractType = "ProposerManyChainMultiSig"
+var ProposerManyChainMultiSigTypeAndVersion = cldf_deployment.NewTypeAndVersion(ProposerManyChainMultiSigContractType, *Version)
+var BypasserManyChainMultiSigContractType cldf_deployment.ContractType = "BypasserManyChainMultiSig"
+var BypasserManyChainMultiSigTypeAndVersion = cldf_deployment.NewTypeAndVersion(BypasserManyChainMultiSigContractType, *Version)
+var CancellerManyChainMultiSigContractType cldf_deployment.ContractType = "CancellerManyChainMultiSig"
+var CancellerManyChainMultiSigTypeAndVersion = cldf_deployment.NewTypeAndVersion(CancellerManyChainMultiSigContractType, *Version)
+
+var Deploy = contract.NewDeploy(contract.DeployParams[ConstructorArgs]{
+    BytecodeByTypeAndVersion: map[string]contract.Bytecode{
+        ProposerManyChainMultiSigTypeAndVersion.String(): { /* ... */ },
+        BypasserManyChainMultiSigTypeAndVersion.String(): { /* ... */ },
+        CancellerManyChainMultiSigTypeAndVersion.String(): { /* ... */ },
+    },
+})
+```
+
+The caller selects the role at deploy time by passing the appropriate `TypeAndVersion` to `Deploy`:
+
+```go
+many_chain_multi_sig.Deploy.Execute(b, chain, contract.DeployInput[many_chain_multi_sig.ConstructorArgs]{
+    TypeAndVersion: many_chain_multi_sig.ProposerManyChainMultiSigTypeAndVersion,
+})
+```
+
+**Rules:**
+- Labels must be valid Go exported identifiers, non-empty, unique, and different from `contract_name`.
+- The list must contain at least one entry; an empty list is rejected.
+- Cannot be combined with `omit_deploy: true`.
+- The base `contract_name` type is **not** included in `BytecodeByTypeAndVersion` when this field is set, and `TypeAndVersion` is not emitted (use the per-label `*TypeAndVersion` vars instead).
