Update DevTools to Material 3

[kenzieschmoll]

Fixes #4601

There is still some polish to land as a follow up and some TODOs I will address, but this is the bulk of the migration.

RELEASE_NOTE_EXCEPTION=[release notes are modified - there is a bug in the check]

[bkonyi]

Some places that need UI polish:

There's some places where the border outline is cut off at the corners (debugger call stack, file explorer, network requests table, logging, etc):

and some buttons with colored backgrounds have invisible text (connection screen, device info dialog):

Text is unreadable in the heap snapshot tab:

We need some padding between the "Clear" and "(?)" buttons under the trace instances tab:

The "File Explorer" button on the debugger page should be a toggle button:

Light theme review:

Selected text contrast is low for table rows with light theme enabled (also there's no alternating colors between rows):

Not sure if this is due to this migration, but the memory chart legend is clipping text:

Logging screen labels have poor contrast:

I think we should consider revisiting our color scheme for the light theme. There's very little color and the colors we do have feel rather harsh:

It feels like Windows high-contrast mode, which I'm not sure is the look we should go for:

Code looks good. I did some testing and found the following issues

• Landing page buttons aren't readable

• Cpu sample rate background is square, but button is round:
  
• Memory page line height seems to cut off the text
  
• Debugger button hover backgrounds are square
  
• Device info button not readable

@kenzieschmoll do you know if these material changes would fix this failure on master?

Those failures look unrelated. Those are for case study apps. Something probably is broken with those apps on the the latest version of the flutter candidate.

For now kenzie is adding a release notes exception to the description to overcome a bug in the release notes workflow.
I've filed an issue for it here.
#5439

Essentially this PR has so many files, and the workflow doesn't support pagination when fetching the list of files modified :P :D

I added fixes for this to this PR. Just changed a couple min sdk constraints on the test fixture and case study apps

@kenzieschmoll I tried this out in VS Code embedded view. Noticed a few minor issues (not sure if they're all related to this change though, or if any are dupes). If you'd rather another issue(s) for these, let me know.

1. Some tooltips are dark text on dark bg (Select Widget Mode, Show Structured Errors)
   
   
2. Might be intended, but tooltip on Refresh Tree (and others, like Report Feedback, ) are opposite colour (dark vs light). Some also have a lot of padding compared to others:
   
   
   
3. Alignment of hyperlinks in About dialog is off
   
4. "Eval" text is truncated when typing an expression in the Memory view:
   
5. Similarly, text in the Legend is truncated the same:
