cmd/go: add //go:embed all:pattern
When //go:embed d matches directory d, it embeds the directory
tree rooted at d, but it excludes files beginning with . and _,
as well as files having problematic names that will not be packaged
into modules (names such as .git and com1).
After long discussions on #42328 and #43854, we decided to keep
the behavior of excluding . and _ files by default, but to allow the pattern
prefix 'all:' to override this default. This CL implements that change.
Note that paths like .git and com1 are still excluded, as they must be,
since they will never be packed into a module.
Fixes #43854.
