readme: encoding_rs's SIMD support is broken

Add a note about it to the README.

Also, remove mention of the avx-accel feature since it no longer exists.
(bytecount now uses runtime detection to enable SIMD support.)

Fixes #1175

============
TODO.
**BREAKING CHANGES**:
* The `avx-accel` feature of ripgrep has been removed since it is no longer
necessary. All uses of AVX in ripgrep are now enabled automatically via
runtime CPU feature detection. The `simd-accel` feature does remain
available, however, it is broken in the latest nightly release of Rust.
See [#1175](https://github.com/BurntSushi/ripgrep/issues/1175) for more
info.
Feature enhancements:
* [FEATURE #1099](https://github.com/BurntSushi/ripgrep/pull/1099):
