COMPMID-3069: Improve build time by splitting up ToolchainSupport.h

Split out the parts of ToolchainSupport coming from <memory> and
the parts coming from <string> into their own new header files.
This accounts for 99% of uses of ToolchainSupport, which means that
expensive header files such as arm_neon.h don't need to be included
everywhere.

Knocks about 10% of compilation time off kernel files.
