frontend: upgrade to Angular 10

[alanorth]

Upgrade frontend to Angular 10 using ngupgrade.

1. First I did Angular itself (note I had to force the install due to peer dependencies):

$ npx @angular/cli@10 update --force @angular/core@10 @angular/cli@10
...
Package "ngx-tour-md-menu" has an incompatible peer dependency to "@angular/animations" (requires ">=7.0.0 <9.0.0" (extended), would install "10.2.5").
Package "ngx-loading" has an incompatible peer dependency to "@angular/common" (requires "^8.0.0" (extended), would install "10.2.5").
Package "@thisissoon/angular-inviewport" has an incompatible peer dependency to "@angular/core" (requires ">=5.0.0 <9.0.0" (extended), would install "10.2.5").
Package "ngx-tour-core" has an incompatible peer dependency to "@angular/router" (requires ">=7.0.0 <9.0.0" (extended), would install "10.2.5").

2. Then I did Angular Material:

$ npx @angular/cli@10 update --force @angular/material@10
...
Package "@material-extended/mde" has an incompatible peer dependency to "@angular/cdk" (requires "^8.0.0 || ^9.0.0-0", would install "10.2.7").
Package "ngx-tour-md-menu" has an incompatible peer dependency to "@angular/material" (requires ">=7.0.0 <9.0.0", would install "10.2.7").

3. Then I did @ngrx/store:

$ ng update @ngrx/store@10

The site builds and runs, including all charts on the homepage. I have not done an extensive check.

Created a new OpenRXV instance based on this Angular 10 branch today and everything seems to work fine once I harvested some items and added a few filters, but there is some log spam:
