Add a second level cache to contain tx batch specific programs

[pgarg66]

Problem

Program management instructions could potentially modify loaded programs by redeployment or closing. Having a separate data structure to contain transaction batch specific loaded program will simplify the code.

Summary of Changes

Add a second level cache to store transaction batch specific program entries. This cache can contain only one program for a given key, that's visible at a given slot. The program management instruction will replace the program entry if the program gets modified.
