Simplify NLS IDs

## Problem This is some source code that uses NLS: ```ts const res = await this._dialogService.confirm({ type: 'info', message: nls.localize('restart1', "Profile Extensions"), detail: nls.localize('restart2', "In order to profile extensions a restart is required. Do you want to restart '{0}' now?", this.productService.nameLong), primaryButton: nls.localize('restart3', "&&Restart"), secondaryButton: nls.localize('cancel', "&&Cancel") }); ``` These NLS calls use hand-crafted IDs. Very often, these IDs are meaningless and we need to add "comments" for the translators anyway. But still, it requires effort and mental energy to come up with these unique IDs. Especially when other IDs are involved, their relationship is unclear: ```ts 'editor.minimap.enabled': { type: 'boolean', default: defaults.enabled, // How does `minimap.enabled` relate to `editor.minimap.enabled`? // Shouldn't the NLS id be `editor.minimap.enabled` too? description: nls.localize('minimap.enabled', "Controls whether the minimap is shown.") }, 'editor.minimap.autohide': { type: 'boolean', default: defaults.autohide, description: nls.localize('minimap.autohide', "Controls whether the minimap is hidden automatically.") }, 'editor.minimap.size': { type: 'string', enum: ['proportional', 'fill', 'fit'], enumDescriptions: [ // Here, proportional refers to the enum value, but doesn't occur in the text. // This could lead to inconsistencies when the enum value is being renamed. nls.localize('minimap.size.proportional', "The minimap has the same size as the editor contents (and might scroll)."), nls.localize('minimap.size.fill', "The minimap will stretch or shrink as necessary to fill the height of the editor (no scrolling)."), nls.localize('minimap.size.fit', "The minimap will shrink as necessary to never be larger than the editor (no scrolling)."), ], default: defaults.size, description: nls.loc…
