improvements on the hot code reloading support (#10892)

Browse source 
* calling the "_actual" versions of functions when defined within the same module - slowdown for the snappy compression is now down from x6 to x4-x5 when HCR is ON
* dynamically linking to the runtime for VS when HCR is on - binaries are smaller
* compilerProcs are also called using the _actual direct version within the module they are defined (system)!
* updated comments & goals
* handling VS-compatible compilers on Windows in a cleaner way
* now the .dll/.so files end up in the nimcache even when --nimcache isn't explicitly stated
