Ingvar Stepanyan 27ae47117e Leverage make -j to parallelise C++ builds
We've been running each Make command in a single thread, resulting in fairly slow builds for C++ codecs.

This change instead runs all `make` invocations with `-j` defaulting to number of cores (retrieved via `nproc`).

On my machine Docker uses a VM configured to 4 cores out of 8 available. This change brings total build time for C++ codecs down from 10m28s to 7m5s (~3.5 minutes difference).

Note (1): I've converted imagequant builds to use built-in `make` as well to leverage this parallelisation and future-proof build script.
Note (2): we don't need to do the same for Rust, since Cargo parallelises builds by default.

Example

API

int version()

Returns the version of libwebp as a number. va.b.c is encoded as 0x0a0b0c

UInt8Array encode(uint8_t* image_buffer, int image_width, int image_height, WebPConfig config)

Encodes the given image with given dimension to WebP.

void free_result()

Frees the last result created by encode().
