Spec: https://fetch.spec.whatwg.org/#ref-for-cross-origin-resource-policy-internal-check
This purpose of this patch is just to implement the spec.
One noticeable thing I did in the patch is I made `CacheResponse` to
include the `credentials mode` of the initial request. Consider the
below scenario:
1. Create a fetch request with a URL and a specific credential_mode, and put it into cache
2. Call cache.match by using a URL, but without credential_mode
3. cache.match() result should be filtered according to the initial request's credential_mode
When applying the `response’s request-includes-credentials is true`
check, the initial request's `credential_mode` is needed because
`request-includes-credentials` is judged by the `credential_mode`.
The rest of the changes are just normal spec alignments.

The biggest set of APIs from ns[T]StringObsolete which are still heavily used
are the string searching APIs. It appears the intention was for these to be
replaced by the `FindInReadable` APIs, however that doesn't appear to have
happened.
In addition, the APIs have some quirks around their handling of mixed character
widths. These APIs generally supported both narrow strings and the native
string type, probably because char16_t string literals weren't available until
c++11. Finally they also used easy-to-confuse unlabeled boolean and integer
optional arguments to control behaviour.
These patches do the following major changes to the searching APIs:
1. The ASCII case-insensitive search method was split out as
LowerCaseFindASCII, rather than using a boolean. This should be less
error-prone and more explicit, and allows the method to continue to use
narrow string literals for all string types (as only ASCII is supported).
2. The other [R]Find methods were restricted to only support arguments with
matching character types. I considered adding a FindASCII method which would
use narrow string literals for both wide and narrow strings but it would've
been the same amount of work as changing all of the literals to unicode
literals.
This ends up being the bulk of the changes in the patch.
3. All find methods were re-implemented using std::basic_string_view's find
algorithm or stl algorithms to reduce code complexity, and avoid the need to
carry around the logic from nsStringObsolete.cpp.
4. The implementations were moved to nsTStringRepr.cpp.
5. An overload of Find was added to try to catch callers which previously
called `Find(..., false)` or `Find(..., true)` to set case-sensitivity, due
to booleans normally implicitly coercing to `index_type`. This should
probably be removed at some point, but may be useful during the transition.

In the testcase, clone() will trigger the first AsyncOpenStreamOnOwningThread() call and shortly after that read() will trigger the second one. For both calls mSnappyStream isn't set yet, and the first one finishes first and get the stream.
When the second run of AsyncOpenStreamOnOwningThread starts, the first run already got the stream and thus OpenStream fails. Then it thinks there should be no stream since it failed, but there is, so assertion fails at line 481.

As serializing IPCStream no longer requires a manager or FileDescriptor array,
the arguments are no longer necessary, and can be removed. The AutoIPCStream
helper can also be removed, as managed actors are no longer used for
serialization, so a delayed start callback is not necessary.
The delayed start parameter is also removed from nsIIPCSerializableInputStream
instances, but is still present as `aAllowLazy` on the toplevel serialization
methods.

This interface should no longer be required due to the changes in part 1
limiting the complexity of IPCStream instances and limiting the number of file
descriptors which a single stream can attach to a message.
Removing this interface is necessary to serialize nsIInputStream instances over
arbitrary toplevel protocols and non-protocol IPC in the future.

This gives us various positive benefits, such as using a shared memory ring
buffer for faster communication, not having data streaming being bound to the
thread which transferred the nsIInputStream (which is often the main thread),
and the ability for some backpressure to be applied to data streaming.
After this change, the "delayed start" parameter for IPCStream serialization is
less relevant, as backpressure will serve a similar purpose. It will still be
used to determine whether or not to use RemoteLazyInputStream when serializing
from the parent process.

Before this change, the collection of typedefs to include in IPDL
protocols was being performed in the _DecorateWithCXXStuff pass of
lower.py. This pass iterates over all included headers, including
recursively, so will also visit headers included by headers you import.
The recursive behaviour caused issues because importing and
forward-declaring imported types is non-recursive, looking at exported
types only one layer deep. This could lead to typedefs being generated
in IPDL protocols referencing types which could never be named by the
IPDL code, and which had no definition in c++, leading to build errors.
This patch changes the logic to instead happen during the
_GenerateProtocolActorCode pass of lower.py, which is also where
required forward declarations and imports are handled, allowing us to
keep the set of typedefs generated more tightly in sync with the actual
set of types available to the actor.
This required some changes in client code which was relying on
incorrectly generated typedefs, however these types have now been fixed.

Due to the earlier changes in this patch series, we now build IPDL files
within the directories which they're declared in, meaning that the
generated ChannelInfo.cpp file made by ChannelInfo.ipdlh will try to
compile a ChannelInfo.o file on top of ChannelInfo.cpp's ChannelInfo.o
file when building in non-unified mode.
This works around the issue by renaming the ipdlh file to
IPCChannelInfo.ipdlh.
