This PR removes the default syntax colors from the theme.
With the changes in #11911 these colors could leak through if the theme
didn't provide a value for that syntax color.
Removing them gives themes a clean slate to work with.

This PR improves the merging behavior for the `SyntaxTheme` such that
user-provided values get merged into the base theme.
This makes it possible to override individual styles without clobbering
the unspecified styles in the base theme.
Release Notes:
- Improved merging of `syntax` styles in the theme.
This PR addresses a TODO comment by making `SyntaxTheme::new_test` only
available in tests.
We needed to make it available when the `test-support` feature was
enabled for it to be used in tests outside of the `theme` crate.
