Arm64/Sve: Missing test coverage for invalid immediate

[kunalspathak]

All the test templates that verify the invalid immediate, is missing this piece of code. Thanks @amanasifkhalid for bringing this to my attention in #104697 (comment).

if (!succeeded)
{
    Succeeded = false;
}

There are also certain templates like _SveImmBinaryOpTestTemplate.template that doesn't even have this test method.

• Need to audit all the *Imm*.template files that were added/updated as part of SVE work and make sure we add test coverage for it.
• Also make sure that we have coverage for following:
  • When we use valid value via constant as the input using {Imm}
  • When we use valid value via variable as the input using Imm
  • When we use invalid valid via constant as the input and we throw ArgumentOutOfRangeException
  • When we use invalid value via variable as the input and we throw ArgumentOutOfRangeException

Assigning to @TIHan for now and we will re-distribute it if needed.
