In my testing, the gopls degraded memory mode (currently set via
"memoryMode": "DegradeClosed") did not save as much memory as expected
due to still type checking all packages in the workspace (even if in
ParseExported mode). It is also annoying to get incomplete results from
references and renaming.
I think we can (and should) fix both problems: don't even consider
packages that aren't 'reachable' via open files, but fully type check
the reverse transitive closure of the packages you're working on. This
CL does exactly that, by swapping out the concept of 'workspace
packages' with 'active packages'.
In testing, this decreased my memory footprint while working on std by
3-4x when compared to normal mode, and 2x when compared to the previous
implementation of DegradeClosed.
It still needs more testing before we move this option out of
experimental.

Before this change directory names were used "as is" for package completion.
It could lead to invalid suggestions (for example, 'package 1abc' or package 'ab-cd').
This change adds a check whether a directory name can be used in a package path.
If the directory name is invalid, only 'package main' will be suggested.
Otherwise, the directory name will be normalized and will be used as a package name.
Note: normalized directory names contain only lower case letters and digits.

It felt a little redundant to have completion duplicated in the file
names. Happy to revert if you prefer it the original way.
