Restore E_NOTIMPL fallback in DacDbiInterfaceImpl::GetContext (#128499)…

… (#128920)

On platforms where ICorDebugDataTarget::GetThreadContext returns
E_NOTIMPL, restore the fallback that walks the thread's Frame chain to
reconstruct a register context from REGDISPLAY. This is needed for
managed debugging stack walks on non-Windows platforms.

The fallback was removed in 5391e9e.

[Release/10.0] Pass down DJI and MethodDesc to avoid unnecessary PtrH…

…ashMap lookup (#126247)

Fixes #126096

main fixes this issue via #123492
- a different approach that's too risky for servicing.
#123651 had tried a targeted
approach and this completes the targeted fix for the path.

# Description

PR #123651 fixed the `GetJitInfo` call in `BindPatch` to avoid a
deadlock-prone `HashMap::LookupValue` -> `GCCoopHackNoThread` ->
`DisablePreemptiveGC` path while holding the DebuggerController lock.
However, the same function has a second call to
`CodeRegionInfo::GetCodeRegionInfo(NULL, NULL, startAddr)` that follows
the exact same deadlock path when `dji` is NULL, `GetCodeRegionInfo`
calls `InitializeFromStartAddress` -> `GetMethodRegionInfo` ->
`EECodeInfo` constructor -> `ReadyToRunJitManager::JitCodeToMethodInfo`
-> `HashMap::LookupValue` -> GC cooperative mode transition.

This one-line fix passes the already-available `info` (DebuggerJitInfo)
and `pMD` (MethodDesc) to `GetCodeRegionInfo`, matching every other
callsite in controller.cpp. When `info` is non-null and has a cached
`m_addrOfCode`, `GetCodeRegionInfo` returns the cached
`m_codeRegionInfo` immediately without constructing an `EECodeInfo`,
avoiding the HashMap and the GC mode transition entirely. The change in
#126249 tries to find other
locations that can face this issue. So far, they are all around the
thread starter added in r2r delay call transitions. This change fixes
most of those cases.

# Customer Impact

Without this fix, customers debugging ReadyToRun applications can
experience debugger hangs. The deadlock occurs when:

1. A thread holds the DebuggerController lock in `BindPatch` (e.g.,
during `MapAndBindFunctionPatches` from `JITComplete` or
`AddBindAndActivateILReplicaPatch`)
2. `GetCodeRegionInfo` constructs an `EECodeInfo` for a R2R method,
entering `HashMap::LookupValue` which transitions to GC cooperative mode
3. A GC or debugger suspension is pending `DisablePreemptiveGC` ->
`RareDisablePreemptiveGC` -> `WaitSuspendEvents` blocks indefinitely
4. Other threads waiting on the DebuggerController lock (or the GC
needing threads at safe points) deadlock

The result is the debugger and IDE hang, requiring force-close and loss
of the debugging session.

# Regression

No. The root cause has existed since ReadyToRun support was added. The
original issue (#123650) notes that timing changes may have made it more
likely to hit recently, but this specific `GetCodeRegionInfo` path has
always been vulnerable. The bug has become a lot more visible in 10.0
nonetheless.

# Testing

- The fix is a single-line change that passes already-available local
variables (`info`, `pMD`) to `GetCodeRegionInfo` instead of `(NULL,
NULL)`, matching all other callsites in controller.cpp (see lines ~6173,
~6219, ~8054 for the same pattern).
- Debugger tests pass with this change.

# Risk

**Very Low.** This is a one-line change that passes two existing local
variables to a function instead of NULL. The `info` and `pMD` variables
are already computed earlier in the same function and used in the lines
immediately surrounding this call. Every other `GetCodeRegionInfo`
callsite in controller.cpp already passes the DJI and MethodDesc. The
only effect is avoiding an unnecessary `EECodeInfo` construction (and
its HashMap lookup) when cached data is available.

Backport of #126211 to release/11.0-preview3

/cc @lewing

## Customer Impact

- [ ] Customer reported
- [ ] Found internally

[Select one or both of the boxes. Describe how this issue impacts
customers, citing the expected and actual behaviors and scope of the
issue. If customer-reported, provide the issue number.]

## Regression

- [ ] Yes
- [ ] No

[If yes, specify when the regression was introduced. Provide the PR or
commit if known.]

## Testing

[How was the fix verified? How was the issue missed previously? What
tests were added?]

## Risk

[High/Medium/Low. Justify the indication by mentioning how risks were
measured and addressed.]

**IMPORTANT**: If this backport is for a servicing release, please
verify that:

- For .NET 8 and .NET 9: The PR target branch is `release/X.0-staging`,
not `release/X.0`.
- For .NET 10+: The PR target branch is `release/X.0` (no `-staging`
suffix).

## Package authoring no longer needed in .NET 9

**IMPORTANT**: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.
