It is illegal to call this method on a deferred context, so we should
filter out those calls. This allows the implementation to make use of
features specific to the immediate context.
Also refactored buffer mapping to reduce code duplication.
Optimized the lookup function for a small performance gain
in games which map a lot of resources on deferred contexts.
* [dxvk] fixes for MSVC
* nullptr -> int is illegal conversion for MSVC. nullptr was replaced with VK_NULL_HANDLE
* MSVC does not support source code strings longer than 65535 chars. String was replaced with array of chars.
* [utils] fixes for MSVC
* __mingw_uuidof() does not exists in MSVC
* apply GCC pragma only for GCC
* added missing header
* [dxbc] fixes for MSVC
