[NFC] Change Key in Argument to a std::string
Before, Key was a StringRef to avoid unnecessary copies. This commit changes
that to a std::string.
This was okay previously because when people called emit for remarks before,
they would create the remark *within* the call to emit. However, if you build
the remark up and call emit *afterward*, it's possible to end up freeing the
memory assigned to the StringRef before the call to emit.
This caused a test failure with https://reviews.llvm.org/D37085 on Linux.
Since building remarks before a call to emit is a valid use-case, it makes
sense to replace this with a std::string.
