Porting TLTs on Xcelium

This issue lists the tests completely/partially passing on VCS and failing on Xcelium.

The list below is "dynamic" and will be updated as things get fixed. It's intended to be a list of buckets that group together common failure modes. In all cases, these are tests that pass for all seeds on VCS but fail for all seeds on Xcelium.

Start with the listed failing tests and reproduce their Xcelium failures, beginning with the assertion location in pwrmgr_slow_fsm.sv:362 and the checks in chip_sw_rom_e2e_base_vseq.sv:37 and chip_sw_rom_e2e_jtag_debug_vseq.sv:94. Compare each result with VCS behavior and group the failures into actionable buckets; done means the listed tests pass on Xcelium or have their remaining failure modes tracked.
