Strip glob patterns from include basePath

[joshcartme]

quick explanation:
Absolute paths like "/some/path/glob/**" were getting through when the correct path would be `"/some/path/glob"``

long:
An include like ../../ambient-types/**/* is turned into an absolute path, let's say /home/dev/project/ambient-types/**/* and passed here

typescript-go/internal/vfs/utilities.go

Lines 241 to 252 in e8d352c

	func getIncludeBasePath(absolute string) string {
	wildcardOffset := strings.IndexAny(absolute, string(wildcardCharCodes))
	if wildcardOffset < 0 {
	// No "*" or "?" in the path
	if !tspath.HasExtension(absolute) {
	return absolute
	} else {
	return tspath.RemoveTrailingDirectorySeparator(tspath.GetDirectoryPath(absolute))
	}
	}
	return absolute[:strings.LastIndex(absolute, string(tspath.DirectorySeparator))]
	}

That strips the last chunk of the path, so returns /home/dev/project/ambient-types/**. Then patterns in

typescript-go/internal/vfs/utilities.go

Line 425 in e8d352c

patterns := getFileMatcherPatterns(path, excludes, includes, useCaseSensitiveFileNames, currentDirectory)

ends up with one of it's base paths as /home/dev/project/ambient-types/** and that is not a valid path to visit in

typescript-go/internal/vfs/utilities.go

Lines 370 to 382 in e8d352c

	func (v *visitor) visitDirectory(
	path string,
	absolutePath string,
	depth *int,
	) {
	canonicalPath := tspath.GetCanonicalFileName(absolutePath, v.useCaseSensitiveFileNames)
	if v.visited.Has(canonicalPath) {
	return
	}
	v.visited.Add(canonicalPath)
	systemEntries := v.host.GetAccessibleEntries(absolutePath)
	files := systemEntries.Files
	directories := systemEntries.Directories

so systemEntries.Files and systemEntries.Directories are empty and any files represented by that include are not found.

Things do work with implicit globs, so if that include was ../../ambient-types the basePath ends up as /home/dev/project/ambient-types and the files and/or directories are found.

This is attempting to address #980
