Readme: improve consitency of compilation steps

Browse Source 
Currently compilation steps use two different types of methods, manual
build directory creation and using meson setup build to directly create
the build directory. This potential makes the new user who wants to
build docs or cross compile confused about which step of compilation the
user is in. This patch aims to make these steps clear.

# Compile
## General compilation steps
1. Install [Meson](https://mesonbuild.com/) (0.49 or higher), [Ninja](https://ninja-build.org/), and, for x86\* targets, [nasm](https://nasm.us/) (2.14 or higher)
2. Run `mkdir build && cd build` to create a build directory and enter it
3. Run `meson setup ..` to configure meson, add `--default-library=static` if static linking is desired
4. Run `ninja` to compile
Following are modification of step 3 and 4, for specific purpose.
## Cross-Compilation for 32- or 64-bit Windows, 32-bit Linux

If you're on a linux build machine trying to compile .exe for a Windows target/host machine, configure meson like this

meson setup build --cross-file=package/crossfiles/x86_64-w64-mingw32.meson
meson setup .. --cross-file=../package/crossfiles/x86_64-w64-mingw32.meson
```
or, for 32-bit:
```
meson setup build --cross-file=package/crossfiles/i686-w64-mingw32.meson
meson setup .. --cross-file=../package/crossfiles/i686-w64-mingw32.meson
```
`mingw-w64` is a pre-requisite and should be installed on your linux machine via your preferred method or package manager. Note the binary name formats may differ between distributions. Verify the names, and use `alias` if certain binaries cannot be found.

## Build documentation
1. Install [doxygen](https://www.doxygen.nl/) and [graphviz](https://www.graphviz.org/)
2. Run `meson setup build -Denable_docs=true` to create the build directory
3. Run `ninja -C build doc/html` to build the docs
1. Make sure [doxygen](https://www.doxygen.nl/) and [graphviz](https://www.graphviz.org/) are installed.
2. Run `meson setup .. -Denable_docs=true` to configure meson to generate docs from the build directory.
3. Run `ninja doc/html` to build the docs
The result can be found in `build/doc/html/`. An online version built from master can be found [here](https://videolan.videolan.me/dav1d/).
