Remove implicit conversion operator from RString to const char*

This is required for the RString to std::string migration.

Mostly automated from https://github.com/aeubanks/rewriter/blob/main/c_str.cc, with some manual intervention required for fixing up `a + b.c_str()` to `(a + b).c_str()`.

Added some overloads for some common global functions like sm_crash to reduce the number of changes required here.
