rename profiles.json to settings.json, clean up the defaults

[DHowett-MSFT]

This pull request migrates profiles.json to settings.json and removes the legacy roaming AppData settings migrator.

It also:

• separates the key bindings in defaults.json into logical groups
• syncs the universal terminal defaults with the primary defaults
• removes some stray newlines that ended up at the beginning of settings.json and defaults.json

Fixes #5186.
Fixes #3291.

sync universal with main

kill stray newlines in template files

move profiles.json to settings.json

This commit also changes Get*Settings from returning a string to
returning a std::filesystem::path. We gain in expressiveness without a
loss in clarity (since path still supports .c_str()).

NOTE: I tried to do an atomic rename with the handle open, but it didn't
work for reparse points (it moves the destination of a symbolic link
out into the settings folder directly.)

(snip for atomic rename code)

auto path{ pathToSettingsFile.wstring() };
auto renameBufferSize{ sizeof(FILE_RENAME_INFO) + (path.size() * sizeof(wchar_t)) };
auto renameBuffer{ std::make_unique<std::byte[]>(renameBufferSize) };
auto renameInfo{ reinterpret_cast<FILE_RENAME_INFO*>(renameBuffer.get()) };
renameInfo->Flags = FILE_RENAME_FLAG_REPLACE_IF_EXISTS | FILE_RENAME_FLAG_POSIX_SEMANTICS;
renameInfo->RootDirectory = nullptr;
renameInfo->FileNameLength = gsl::narrow_cast<DWORD>(path.size());
std::copy(path.cbegin(), path.cend(), std::begin(renameInfo->FileName));

THROW_IF_WIN32_BOOL_FALSE(SetFileInformationByHandle(hLegacyFile.get(),
                          FileRenameInfo,
                          renameBuffer.get(),
                          gsl::narrow_cast<DWORD>(renameBufferSize)));

(end snip)

Stop resurrecting dead roaming profiles

I guess I should update my PR for WT env vars?

[DHowett-MSFT]

Yeah! That'd be excellent.
