Refactored virtual allocator. (COMPATIBILITY BREAKING!) Added TLSF algoritym.

Browse source 
Refactored virtual allocator: Added type VmaVirtualAllocation, member VmaVirtualAllocationInfo::offset, changed parameters of vmaVirtualAllocate, vmaVirtualFree, vmaSetVirtualAllocationUserData, vmaGetVirtualAllocationInfo.

Added TLSF algorithm: Added VMA_POOL_CREATE_TLSF_ALGORITHM_BIT, VMA_VIRTUAL_BLOCK_CREATE_TLSF_ALGORITHM_BIT.

Some internal refactoring.

Improved documentation: Grouped API elements into Doxygen modules.

Code mostly by @medranSolus.

Usage</h1>
<p >After following steps described above, you can create buffers with <code>VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT*</code> using VMA. The library automatically adds <code>VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT*</code> to allocated memory blocks wherever it might be needed.</p>
