Creation of AppJit snapshot will not include the source of [Script]
objects (see `UntaggedScript::snapshot_to`). As a result there's no
point in letting the CFE embed the sources into the kernel if we
only use it to create an AppJit snapshot.
This is also in line with build rules for our dart-sdk, where we do the
kernel compilation separately, see utils/application_snapshot.gni:
```
template("application_snapshot") {
...
# Build the kernel file using the prebuilt VM to speed up the
# debug and simulator builds.
prebuilt_dart_action(target_name + "_dill") {
...
args = [
...
"--no-embed-sources",
...
]
[[[
}
...
}
```

When VM starts, it will try to find kernel service snapshot which is located together with exe file. However, if symbolic link is provided, the directory to search will become the parent directory of link but not the actual target.

Prior to this change, on Linux, if one created a symbolic link to the
dart executable and ran that, the kernel-service snapshot would not be
found. This has the effect of compiling the input script on a
non-trained kernel service, meaning the startup is slower.
This is particularly bad as the debian install of dart creates a symbolic
link to dart as /usr/bin/dart with the target being /usr/lib/dart/bin/dart
meaning that for instance running a hello-world script like one normally
would, `dart hello.dart` would take something along the lines of 3-4 times
longer than if running `/usr/lib/dart/bin/dart hello.dart`.
On my Pixelbook (in crostini) this is ~755 ms vs ~210 ms.
This change does *NOT* fix it on other platforms.

Towards #37610
When the `script_uri` argument to the VM has no path separators the
value returned from `DirName` is identical to the input, and it is not
safe to use it as a prefix for concatenating relative paths.
- Compare the dirname against the script URI and use an empty prefix
when they match, indicating we were unable to find a directory.
- Rename `absolute_filename` to `resolved_filename` since it is not
absolute in all cases.
