Add support for some new CSS rules (#2115, #2116, #2117)

This release adds support for @font-palette-values, @counter-style, and @font-feature-values. This means esbuild will now pretty-print and minify these rules better since it now better understands the internal structure of these rules:

Upgrade to Go 1.18.0 (#2105)

Binary executables for this version are now published with Go version 1.18.0. The Go release notes say that the linker generates smaller binaries and that on 64-bit ARM chips, compiled binaries run around 10% faster. On an M1 MacBook Pro, esbuild's benchmark runs approximately 8% faster than before and the binary executable is approximately 4% smaller than before.

This also fixes a regression from version 0.14.26 of esbuild where the browser builds of the esbuild-wasm package could fail to be bundled due to the use of built-in node libraries. The primary WebAssembly shim for Go 1.18.0 no longer uses built-in node libraries.
