- Make cDac implement `ISOSDacInterface2`
- Add `Exception` (managed type) to data descriptor
- Add `GetExceptionData` to `Exception` contract which gets all the data that SOS-DAC API uses

Add the following standard tags to the HTTP Request Activities started in DelegatingHandler:

http.request.method
http.request.method_original
server.address
server.port
url.full

error.type
http.response.status_code
network.protocol.version

Just like in #103769, url.full is being redacted by removing UserInfo and the query string, while exposing a System.Net.Http.DisableQueryRedaction switch for opting-out from the latter.

Since Windows 10 Build 20348, there is a new API to get the temporary files path called [`GetTempPath2`](https://learn.microsoft.com/windows/win32/api/fileapi/nf-fileapi-gettemppath2w). This API returns a directory inaccessible to non-SYSTEM processes if the calling process runs as SYSTEM, and [it is recommended to call this function instead of `GetTempPath`](https://learn.microsoft.com/windows/win32/api/fileapi/nf-fileapi-gettemppathw#remarks).

This PR tries to find `GetTempPath2A` / `GetTempPath2W` and uses that, otherwise it falls back to `GetTempPathA` / `GetTempPathW`.

*Note:* this PR removes an unused function `GetTempPathWrapper` that which referenced `GetTempPathW`

…-init (#104593)

Locals that are in registers at the beginning of a function do not need
to have their stack home zeroed. `genFnProlog` already skips these
locals when computing the range of bytes to zero; however,
`genZeroInitFrame` was not doing the same in the non-block init case,
which does not make use of the range computed by `genFnProlog`. This
could cause an unbounded amount of (unnecessary) codegen during
zero-initing, which is not legal to have in the prolog.

Fix #104570

…104616)

The recent work to allow more retbuf definitions uncovered cases where
we would end up with the retbuffer aliasing an implicit byref argument.
The JIT does not handle this aliasing, which would require proper
`GTF_GLOB_REF` flags on the local nodes accesses implicit byrefs. Fix
the problem by disallowing last-use copy elision when the local would
alias the return buffer.

Fix #104613

Recognizing a series of handle compares as a switch is not legal since
those handles may change values.
