Change the Yarn PnP manifest to a singleton (#2463)

Previously esbuild searched for the Yarn PnP manifest in the parent directories of each file. But with Yarn's enableGlobalCache setting it's possible to configure Yarn PnP's implementation to reach outside of the directory subtree containing the Yarn PnP manifest. This was causing esbuild to fail to bundle projects with the enableGlobalCache setting enabled.

To handle this case, esbuild will now only search for the Yarn PnP manifest in the current working directory of the esbuild process. If you're using esbuild's CLI, this means you will now have to cd into the appropriate directory first. If you're using esbuild's API, you can override esbuild's value for the current working directory with the absWorkingDir API option.

Fix Yarn PnP resolution failures due to backslashes in paths on Windows (#2462)

Previously dependencies of a Yarn PnP virtual dependency failed to resolve on Windows. This was because Windows uses \ instead of / as a path separator, and the path manipulation algorithms used for Yarn PnP expected /. This release converts \ into / in Windows paths, which fixes this issue.

Fix sideEffects patterns containing slashes on Windows (#2465)

The sideEffects field in package.json lets you specify an array of patterns to mark which files have side effects (which causes all other files to be considered to not have side effects by exclusion). That looks like this:

"sideEffects": [
  "**/index.js",
  "**/index.prod.js"
]

However, the presence of the / character in the pattern meant that the pattern failed to match Windows-style paths, which broke sideEffects on Windows in this case. This release fixes this problem by adding additional code to handle Windows-style paths.
