Add RemoveIf to attribute map, and rename Delete to Remove

[dashpole]

Description:

Fixes #4756 by adding RemoveIf for AttributeMap. The implementation (and TODO) are based on the RemoveIf for AttributeValueSlice: https://github.com/open-telemetry/opentelemetry-collector/blob/model/v0.43.1/model/pdata/generated_common.go#L181

Testing:
Unit tests added.

Benchmark added to compare performance of Remove to RemoveIf when deleting a large number of elements.

LGTM, @codeboten @tigrannajaryan since this changes a bit more specifically Delete -> Remove, I want your opinion.

[tigrannajaryan]

No strong opinion on Delete vs Remove name. Works either way for me.

Correction: Remove/RemoveIf is preferable to be consistent with slices that have RemoveIf.

I think GC might actually be handling this correctly, and not leaking memory. My experimental code: dashpole/dashpole_demos@3a2c768#diff-f48531acb0ca1af513103682c6d325f99a4397db9023fa8a3bad4f4700e867a2R9

Thanks for confirming!
