fix: Dataview-format parses 'Task.id' and 'Task.dependsOn' same as emoji

[claremacrae]

Description

Several fixes to the parsing of ids and dependsOn values in dataview format.

• dependsOn is now read
• dependsOn now allows capitals in IDs
• id now allows capitals in IDs

This makes these fields consistent with the parsing of Tasks Emoji format.

Motivation and Context

Fixes #2667, and some other issues found when writing tests

How has this been tested?

• Adding new tests, which initially failed
• Exploratory testing, including confirming that the sample markdown in dependsOn values not read in Dataview format #2667 now works.
