[release/6.0] Fix VN incorrect optimizations with a new JitEEInterface function. (#58005)

* Add/return tests.

* improve the test naming.

* Add a new JitEE method.

with a naive implementation so far.

* Handle generically dissimilar type concerns as well as handle derived type case in the managed compiler

* Fix the field and Unsafe issues.

* fix some failures.

It appeared that we have many trees where we generate unique VN for rhs and don't inform `fgValueNumberBlockAssignment` about it.
For example, for
```
N005 ( 10,  8) [000033] -A--G---R---              *  ASG       struct (copy)
N004 (  3,  2) [000031] D------N----              +--*  LCL_VAR   struct<eightByteStruct, 8> V01 loc1         d:2
N003 (  6,  5) [000030] n---G-------              \--*  IND       struct
N002 (  3,  3) [000043] ------------                 \--*  ADDR      byref
N001 (  3,  2) [000044] -------N----                    \--*  LCL_VAR   struct<largeStruct, 32> V00 loc0         u:6 (last use)
```
we will generate unique rhs but then `fgValueNumberBlockAssignment` will still try to work it as with a non-unique one.

* Fix an oooold bug in VN.

For a tree like:
```
N005 ( 11, 10) [001400] -A------R----             *  ASG       long
N004 (  6,  5) [001401] *------N-----             +--*  IND       long
N003 (  3,  3) [001402] -------------             |  \--*  ADDR      byref  Zero Fseq[_00]
N002 (  3,  2) [001403] U------N-----             |     \--*  LCL_VAR   struct<System.Runtime.Intrinsics.Vector128`1[Byte], 16> V45 tmp38        ud:3->4
N001 (  1,  1) [001404] -------------             \--*  LCL_VAR   long   V69 tmp62        u:2 (last use)
```
SSA was working correctly and printing that `001403` is using SSA-3 and defining SSA-4. However, this code, for some reason, was writing result as a define for SSA-3.

* Add new test cases and a fix for them.

* correct a test copy paste

* response review.
