Aliaksandr Kalenik d54cab60a8 LibWeb/WebGL: Define Float32List exactly like in the spec 
Use `Float32Array or sequence<GLfloat>` instead of
`BufferSource or sequence<GLfloat>`. This meaningfully changes behavior
for `Float16Array` and `Float64Array`: they are now converted to
`sequence<GLfloat>` by iterating the typed array, rather than being
treated as a `BufferSource`. As a result, many WebGL calls now work
correctly where we previously crashed in `VERIFY_NOT_REACHED()` due to
the assumption that a `BufferSource` was always a `Float32Array`.
