Lock uniform buffer only 1 times per each render + minor fixup of uniforms

Lock uniform buffer only 1 times per each render + minor fixup of uniforms

1. Don't lock-unlock Graphics::Memory for each properties.
This patch lock stand-alone uniform buffer map and unlock only few times during rendering.
(We called this API as ReadyToLockUniformBuffer and UnlockUniformBuffer)

It will reduce Renderer::Render time near 6%

2. Don't convert from std::string_vew to std::string
when we get uniform map info from shader

3. Make BufferPropertiesFlags as input of UniformBuffer Constructor
