Improve performance of validateCardanoTx

[koslambrou]

Description

As a plutus-apps emulator user

I want an efficient version of validateCardanoTx

so that I waste as little time as possible when I run the emulator.

Technical details

After the first investigation of https://input-output.atlassian.net/browse/PLT-1026 (emulator performance regression following merge from next-node to main), validateCardanoTx takes 8% of the time of a whole plutus-use-cases run.

Here is an excerpt of the prof file that illustrates the costs of the calls inside validateCardanoTx:
