[Rebase & FF] 202405: BaseTools/WinRcPath: Improve Performance.

[apop5]

Description

WinRcPath generally takes about 2 seconds to run, due to calling multiple .bat files behind the scenes. This change reduces this time to ~0 seconds due to the following changes:

1. It will attempt to load the path from the cache, which is located a $(WORKSPACE)/Conf/.rc_path. If the loading is a success and the rc_path still exists, it will use it.

2. If the cache did not exist, or the path provided by the cache does not exist, it will find the rc path via the .bat files. If that succeeds, it will write the path to the cache.

How This Was Tested

1. Confirmed the plugin will create a cache file on first run and use itin later runs
2. Confirmed updating the path in the cache to a wrong value will invoke the typical means to find the cache and save the correct path into the cache.
