Description:
This patch fixes the issue of possible M20K functional failure after partial reconfiguration on Agilex devices.

This patch also addresses the following internal error that the Fitter may encounter on Agilex devices: 
Internal Error: Sub-system: U2B2_CDB, File: /quartus/db/u2b2/u2b2_re_network_checker.cpp, Line: 174
[Issue tracking number: 15012086354]


Patch# 0.45: 
 This patch addresses the following internal error that the Fitter may encounter on Agilex devices during the retime stage:
Internal Error: Sub-system: LAB, File: /quartus/legality/lab/lab_fm_40_config_creator_module.cpp, Line: 1513 

Patch# 0.66: 
 While populating hipis into the netlist at the end of routing stage, we did not handle the cross partition hipis correctly. It is an edge case which has already been fixed in 22.3. Special check has been added in the patch to handle the cross partition hipis and avoid modifying/touching them. 

Patch# 0.70: 
 None
