Implement `toMatchSnapshot()` (#2294)

* buggy snapshot

* error output for failed snapshot

* missing first

* hints

* open dir once, better cleanup

* update flag

* truncate on update

* object and class snapshot formatting

* array formatting

* no function name, single item is empty array

* string objects, maps, sets, promise

* avoid using invalid memory

* handle number objects

* handle extending `Number`

* boolean objects

* snapshot tests and test updates

* snapshot format for buffers

* safer snapshot parsing

* property matchers setup

* strings and tests

* generate classes with empty prototype

* optional `propertyMatchers` parameter

* new test folder structure

* strings.eqlLong

* globalObject.throwPretty() and expect.any tests

* add updateSnapshot flag to help

* move snapshot format out of `printErrorlikeObject`

* empty object snapshot format

* separate typed array, remove trailing comma

* use `isCell`, object trailing commas

* handle unicode

* todo for primitive constructors

* switch to `JSC.Node.Syscall.open` and `JSC.Maybe`

* use js parser for snapshot files

* deinit ast, log parse error

* copy/paste most of `exports.ZigConsoleClient`

* remove snapshot option

* remove ordered properties option

* remove snapshot format option from `exports.zig`

* remove extra newlines

* change mode

* update test runner output

* escape backticks faster

* `bunx jest` in temp dir

* remove buffered writer

* add `toMatchSnapshot` to types

* cleanup, switch to `pread`

* cli `--update` flag

* `--update-snapshots`

* remove string object format
