Map Ostracon:ErrTxInMap to lbm-sdk:ErrTxInMempoolCache

[Mdaiki0730]

Description

lbm-sdk needs to be mapped for new errors in ostracon(ErrTxInMap).
For this error, lbm-sdk maps errors in types/errors/errors.go to make it easier for users to handle.

An implementation concern is whether ErrInTxMempoolCache fully explains this error.

• For cosmos-sdk compatibility and lbm-sdk interface retention
• "ErrInTxMempoolCache" is insufficient, but the message "tx already in mempool" is enough to explain

For this reason, I mapped it to ErrTxInMempoolCache, but I think renaming this error to ErrTxInMempool is also a way.
