Deprecation info support in RuntimeMetadataIR (#4851)

### Description: 
* Adds `DeprecationStatusIR` enum to sp_metadata_ir.
Deprecation info for simple items.
* Adds `DeprecationInfoIR` enum to sp_metadata_ir.
It is a deprecation info for an enums/errors/calls. Contains
`DeprecationStatusIR`.
Denotes full/partial deprecation of the type or its variants/calls
* Adds `deprecation_info` field to 
       - `RuntimeApiMetadataIR`
       - `RuntimeApiMethodMetadataIR`
       - `StorageEntryMetadataIR`
       - `PalletConstantMetadataIR`
       - `PalletCallMetadataIR`
       - `PalletMetadataIR`
       - `PalletEventMetadataIR`
       - `PalletErrorMetadataIR`

### Testing done: 
- Unit tests to check whether or not correct `note`/`since` texts are
getting propagated to the metadata structs.
- UI test to check for error message in case of incorrect attribute
usage.
There's also some test updates to make sure that deprecation attributes
are getting propagated to the relevant structs.
