Add annotations for nullability and length

Browse Source 
These are only present on the declarations in the C API.

New macros
- `VMA_NULLABLE`
- `VMA_NOT_NULL`
- `VMA_NULLABLE_NON_DISPATCHABLE`
- `VMA_NOT_NULL_NON_DISPATCHABLE`
- `VMA_LEN_IF_NOT_NULL`

On clang `VMA_NOT_NULL` and `VMA_NULLABLE` are defined as `_Nonnull` and
`_Nullable`. Clang will use these annotations to generate diagnostics
when these functions or structs are incorrectly used.

`VMA_NULLABLE_NON_DISPATCHABLE` and `VMA_NOT_NULL_NON_DISPATCHABLE` are
not defined on platforms where Vulkan's non-dispatchable handles are not
pointers; on platforms where they are, these macros are defined to be
`VMA_NULLABLE` and `VMA_NOT_NULL` respectively.

`LEN_IF_NOT_NULL` is not defined for any compiler. It is included to
mirror the `len` attribute in the Vulkan XML spec in order to aid in
development of other language bindings for this library.

It was tempting to use C's array syntax (`foo(int len, int arr[len])`)to
specify lengths, however this is not possible to use with optional
pointers, nor is it possible to use inside structs. For the sake of
consistency only `VMA_LEN_IF_NOT_NULL` is used (additionally neither
clang not gcc generate warnings for function misuse when the array
length specifier is anything but an integer literal).

- Also correct a couple of typos
- Also add assert on ppName in vmaGetPoolName

Closes #114
