Implement ISOSDacInterface::GetJitManagerList in cDAC SOSDacImpl

[Copilot]

• Implement ISOSDacInterface::GetJitManagerList in cDAC SOSDacImpl
• Rename GetJitManagerInfo to GetEEJitManagerInfo per review feedback
• Fix cdac_data EEJitManagerPtr to use typed pointer (matching SystemDomain pattern)
• Investigate and fix CI failure: data descriptor does not evaluate to a constant
• Run code review
• Run CodeQL security check

Pull request overview

Implements the cDAC-side ISOSDacInterface::GetJitManagerList by plumbing the EEJitManager address and heap list through CoreCLR data descriptors into the managed ExecutionManager contract, then consuming it from SOSDacImpl with DEBUG legacy-DAC comparison.

Changes:

• Add CoreCLR data descriptor support for EEJitManager::m_pAllCodeHeaps and expose a global pointer to ExecutionManager::m_pEEJitManager.
• Add JitManagerInfo + GetEEJitManagerInfo() to the managed IExecutionManager contract and implement it in ExecutionManagerCore.
• Update SOS COM interface/implementation to use a typed DacpJitManagerInfo and add contract-level unit tests + documentation updates.

@copilot , use the CI-Analysis tool to look at the runtime-diagnostics pipeline failures. There is a problem that one of the datadescriptors added does not evaluate to a constant.
